A Correct answer
Explanation

The series multiplies each term by successive prime numbers and subtracts increasing values: 141×2-?=285, 285×3-?=859, 859×4-?=3441, 3441×5-?=17211. The pattern continues: 17211×6-251=103273 (since 6 is next prime, and subtract 251 which is next in sequence). Option A (103273) is correct.
