A Correct answer
Explanation

PRESCRIBE has 9 letters with 'E' repeated twice. Arrangements = 9! / 2! = 362880 / 2 = 181440. Wait - this doesn't match option A (90720). Let me recount: P-R-E-S-C-R-I-B-E has 9 letters with R and E each repeated twice. So 9! / (2! × 2!) = 362880 / 4 = 90720. Option A is correct. Option B (362880) ignores repeated letters, and options C and D are incorrect.
