• A. $371$
• B. $175$
• C. $271$
• D. $287$

Answer 1

The correct option is C $271$

Option (C) is the correct answer.
Explanation:
The next number in the series is multiplied by 2 and added by 1.
$16\times 2=32+1=33$
$33\times 2=66+1=67$
$67\times 2=134+1=135$
Hence next number will be $135\times 2=270+1=271$
