The correct answer is D. V.
The missing character is the one that completes the following pattern:
- The first letter of the month is the same as the first letter of the number of days in the month.
- The second letter of the month is the same as the second letter of the number of days in the month.
- The third letter of the month is the same as the third letter of the number of days in the month.
The only month that fits this pattern is February, which has 28 days. The first letter of February is F, and the first letter of 28 is V. The second letter of February is e, and the second letter of 28 is e. The third letter of February is b, and the third letter of 28 is r.
A. D is not the correct answer because the first letter of April is A, and the first letter of 30 is A. The second letter of April is p, and the second letter of 30 is p. The third letter of April is r, and the third letter of 30 is r.
B. M is not the correct answer because the first letter of May is M, and the first letter of 31 is M. The second letter of May is a, and the second letter of 31 is a. The third letter of May is y, and the third letter of 31 is y.
C. P is not the correct answer because the first letter of June is J, and the first letter of 30 is J. The second letter of June is u, and the second letter of 30 is u. The third letter of June is n, and the third letter of 30 is n.
D. V is the correct answer because the first letter of February is F, and the first letter of 28 is V. The second letter of February is e, and the second letter of 28 is e. The third letter of February is b, and the third letter of 28 is r.
