23. Three girls from Euclid High School are on the school's softball team.

Shayla says: “All three of our uniform numbers are two-digit prime numbers. The sum of your two uniform numbers is today's date.” (Note: Consider only the date, not the month or year. The same applies below.)

Buffy says: “The sum of your two uniform numbers is my birthday, and it is earlier than today's date.”

Kaitlyn says: “What a coincidence, the sum of your two uniform numbers is my birthday, and it is later than today's date.”
Then Kaitlyn's uniform number is ( ).
(A) 11
(B) 13
(C) 17
(D) 19
(E) 23
23. A.

Notice that the maximum value of a date in a month is 31, and the smallest three two-digit prime numbers are $11, 13, 17$, their pairwise sums are $24, 28, 30$.
From the problem, we know that Katelyn's team jersey number is 11.
