No problem you can write
No problem
you can write down all activities with their durations and series of paths
for example
Activity Dur
A 2
B 5
C 6
D 8
E 5
Now paths like
A-C-D -E
B-C-E
On this basis a network diagram can be sketched and can be answered.
There any relation like FS/FF/SS OR LEAD/LAG canbe mentioned.

Here are paths and their
Here are paths and their durations:
Path Duration
A-B --->3
A-E ---> 2
B-C ---> 4
C-D ---> 3
D-H ---> 3
E-C ---> 5
E-F ---> 4
F-G ---> 4
C-G ---> 2
G-H ---> 4

PATH
AEFGH = 14
All other path have 13 days
hence activitIES on critical path=
AEFGH
HENCE OPTION D IS ANSWER

Above presentation is
Above presentation is example of AOA method.
Here option are given like - A E F C are not activities, but this are nodes.
hence figure only as above.
In this method drawbacks is that - forward and backward passes can not be indicated.
Hence AON is better than this. In PMP generally this AON method is asked, like in case of ES/ EF/LS/LF.
Above example can be solved by AON like this:

Thank You Sir. I was mainly
Thank You Sir. I was mainly having problem to convert these paths to activites and to get the end. Now i got it.
