Figure shown below is described by equation—
-
-
3 dv + v + i = 0 4 dt 4 2 -
3 dv + v - i = 0 4 dt 4 2 -
4 dv + v + i = 0 3 dt 4 2 -
4 dv + v - i = 0 3 dt 4 2

Correct Option: B
The given circuit: 
Applying source transformation in the given circuit
Ceq = 1|| (1 + 2) = 3/4 F
Applying KCL at node A in the above circuit
| + | = | ||||
| 4 | dt | 4 | 2 |
or
| + | - | = 0 | ||||
| 4 | dt | 4 | 2 |
Hence alternative (B) is the correct choice.
