A) 35
B) 45
C) 55
D) 85

Correct Answer:

A) 35

Description for Correct answer:
\( \Large 15\times 37\times 63\times 51\times 97\times 17 \)

= \( \Large 255\times 37\times 63\times 51\times 97 \)

= \( \Large 35\times 21 \) [last two digits]

=735=35 [last two digits]

Hence, last two digits of the product is 35.
