Solution

The correct option is A $98 a . m . u .$
$M o l e c u l a r m a s s = m a s s o f h y d r o g e n a t o m \times n u m b e r o f a t o m s + m a s s o f s u l f u r a t o m \times n u m b e r o f a t o m s + m a s s o f o x y g e n a t o m \times n u m b e r o f a t o m s$
Molecular mass of $H_{2} S O_{4} = 1 \times 2 + 32 \times 1 + 16 \times 4 = 98 a . m . u .$
Option A is correct.
