U.S. House Speaker Paul Ryan and Senator Lindsey Graham have joined a growing chorus of Republican leaders to disavow comments by presumptive Republican presidential nominee Donald Trump about the Mexican heritage of a judge in a class-action lawsuit against Trump University.
Questioned Tuesday about Trump's comments, Ryan said "I regret those comments he made. Claiming a person can't do their job because of their race is sort of like the textbook definition of racism." But he did not retract his endorsement of Trump, made last week, and he said he does not believe Democratic challenger Hillary Clinton is "the answer."
Ryan made his comments during an appearance at a women's shelter in Washington, D.C.
In a New York Times interview, Graham, also a former presidential candidate, said Trump's remarks were "the most un-American thing from a politician since Joe McCarthy," referring to the ultra-conservative senator of the 1950s who fueled fears of widespread communist subversion in the United States.
Graham also suggested that Republicans who have endorsed Trump reconsider their choice. "If anybody was looking for an off-ramp, this is probably it," he said.
The backlash appears to be mounting against the candidate, who has repeatedly said he believes U.S. District Court Judge Gonzalo Curiel, because of his "Mexican heritage," would not rule fairly in the case charging Trump with fraud. Curiel is an American who was born and raised in the Midwestern U.S. state of Indiana.
U.S. Senator Ben Sasse, a Republican from Nebraska who has criticized Trump on multiple occasions during the campaign, tweeted: "Saying someone can't do a specific job because of his or her race is the literal definition of 'racism.'''
Sasse was joined Monday by two former rivals for the Republican nomination. Ohio Governor John Kasich tweeted that Trump's offensive "is flat out wrong.'' Trump, Kasich wrote, should "apologize to Judge Curiel & try to unite this country.''
Graham probably believes that:
Pick the correct answer from the following options:

A. Trump should talk to him regarding political matters

B. Trump should be impeached

C. not enough information

D. Trump should only be in office 4 years
B
The context of the situation is that a Republican Senator has said negative things about Donald Trump. We can infer from this statement, as well as his comparison of Trump to Joe McCarthy - someone who was very controversial in politics for being an ultra-conservative and fueling fears of widespread communist subversion in America during the 1950s - that Graham does not think highly of or support Trump's political views. 
Given these factors, it would be unlikely that Graham believes "Trump should talk to him regarding political matters", because he thinks so negatively about Donald Trump (answer A). Because he seems to have strong opinions against Trumps rhetoric and actions, we also know that answer D ("Trump should only be in office 4 years") is incorrect since by answering correctly you must select just one choice out all options.
