Hello Yahowmy88,
do you realize that you are asking about a question on Fortinet Fortigate firewalls in Cisco forums ?
I agree that for a Cisco device the correct answers should be C,D however, Fortinet implementation of static routes is different from the Cisco one.
Fortinet can use not only admin distance with static routes but also the priority concept. Lowest priority is preferred.
All static routes with same admin distance are considered active but only those with lowest priority are used.
Hope to help
Giuseppe
