In the following non planar graph number of independent loop equations are
Answer: Option
Explanation:
Number of independent loop equations are given by,
L = B - N + 1
where L : No. of loop equations
B : No. of branches = 12
N : No. of nodes = 8
L = 12 - 8 + 1 = 5.

I don't know which is node and branches so explain thus concept.

Node:
A point or junction where two or more circuit's elements (resistor, capacitor, inductor etc) meet is called Node.
Branch:
That part or section of circuit which locate between two junctions is called branch. In branch, one or more elements can be connected and they have two terminals.
Loop:
A closed path in circuit where more than two meshes can be occurred is called loop i.e. there may be many meshes in a loop, but a mesh does not contain on one loop.
Mesh:
A closed loop which contains no other loop within it or a path which does not contain on other paths is called Mesh.

Planar graph that can be drawn without edges that intersects within a plane.
Non planar graph that cannot be drawn without edges that intersects within a plane.
Non planar graph that cannot be drawn without edges that intersects within a plane.
