C. is correct.
Based on the show ip ospf output from R1 and R2, R1 and R2 will not form an OSPF neighbor adjacency because of a mismatch in the Hello/Dead Interval. This is because the Hello interval on R1 is 10 seconds and the Hello interval on R2 is 20 seconds. The Hello and Dead interval must match (along with other factors) before OSPF will form a neighbor adjacency.

Although it is a bad question, I think the answer should be D. There are two requirements that if they are not configured correctly will result in having OSPF neighbors but not adjacency. And those two are MTU settings and OSPF network types.
So, I assume the question asks “R1 & R2 are not neighbor as configured but what changes to these configurations will result in establishing neighbor but bot adjacency”.
And the hello/dead timer is just misleading.
