Answer:

  (b)  8

Step-by-step explanation:

We assume that a path must not repeat any node. (So, loops at G are forbidden.)

There are 2 paths through B to A.

There are 2 paths through D to A, so a total of 4 ways to get from C to A.

There is one path from A to H.

There are two paths from H to F, and one path from F to E.

The total number of possible paths is (4)(1)(2)(1) = 8.

Here is a list.
