Correct option is A)

the titration reaction is:Ba(OH)2​+2HCl⟶BaCl2​,+H2​OAccording to the reaction, the formula for a balanced equation isNo.ofmoleculesofBa(OH)2​
VolumeofBa(OH)2​×Molarity​=No.ofmoleculesofHCl
VolumeofHCl×Molarity​
=1
25×MolarityofBa(OH)2​​=2
35×0.1​Therefore, molarity of barium hydroxide =0.07
