ok I will try
Correct option is
B
1.5 V
emf=I(R+r)−−−(a)
WhenI=0.5,R=2ohm
we know that,
emf=V
Therefore Eq(a)become V=0.5(2+r)=>1/2(2+r)
2V=2+r−−−(1)
WhenI=0.25,R=5ohm
Therefore Eq(a)become
V=0.25(5+r)=>1/4(5+r)
4V=5+r−−−(2)
Subtract eq(1) from (2)
4V−2V=5+r−2−r
2V=3
V=3/2
V=1.5v
Hence, the option B is the correct answer.
