B

Explanation:

C and D can be eliminated without much trouble. The scientific method has nothing to do with ease or difficulty of replication. All that is required is that the method shows that replication is possible. Many times the point is to show that a previous hypothesis is incorrect.

So the choice is between A and B. I think your best choice is B although A is also a possibility. Replication is always important.
