Dibasic acids mean acids have two ionizable hydrogens.

gram eq. of OH- = mole \times n-factor = 0.04 \times 1 = 0.04

The Law of equivalence we get,
milli equivalents of acid = milli equivalents of base

N1 X V1 (ACID) = ( meq. of base)

0.1×V = ( meq. of base)

0.1 X V = ( meq. of base) = 0.04 \times 1000

V x 0.1  = 40
V = 400ml

Therefore, Option(2) is correct
