Answer:

Correct option is A)

Let us assume voltmeter is ideal:-It means voltmeter has infinite resistance and current will not flow in voltmeter.

R

eq

in upper branch = R

eq

in lower branch. So current will get equally divide into both branches.

V

A

−V

B

=4×1(1)

V

A

−V

D

=16×1(2)

Subtract 2 and 1

V

B

−V

D

=12V

A voltmeter will read 12 V
