Solution

The correct option is C 19.999 V
$4 \frac{1}{2} d i g i t d u a l s l o p e D V M h a s 5 d i g i t s$

First digit will have, 0 and 1 only all others will have 0 through 9.

$∴ A 0 - 10 V, 4 \frac{1}{2} d i g i t d u a l s l o p e i n t e g r a t i n g D V M c a n r e a d u p t o 19.999 V .$
