Solution

The correct option is C C
Given :
Two current carrying wires are carrying current as shown.

Solution:
According to right hand thumb rule at C position the field intensity{ $\to B$ } will be in same direction that is downwards.
In case of B and E it will cancel each other and for A and D distance is high.

So, correct opt: C
