824517284842282698454832843183

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

Answer: (D)

$4$

Divisors of 8 are 1, 2, 4, 8

so either 1, 2, 4, or 8 should come before and after 8 in the given series.

$824517\underset{–}{28484}2\underset{–}{282}69845483\underset{–}{284}3183$

So 4 occurrences in the given series.

option D
