R is the set of positive even integers less than 51, and S is the set of the squares of the integers in R. How many elements does the intersection of R and S contain ?	Choose the correct choice from the following
A) None B) Three C) Four D) Five E) Seven
R is the set of positive even integers less than 51, and S is the set of the squares of the integers in R.   How many elements does the intersection of R and S contain?   R=2,4,6,8,10,12...   S=4,16,36,64...   Numbers: 4, 16, and 36 are even integers (less than 51) that are in both sets.   Solution: Three   Answer: Three
<result>B</result>
R is the set of positive even integers less than 51, and S is the set of the squares of the integers in R. How many elements does the intersection of R and S contain ?
