Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.904\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:

b. Cc1cccc(OCCn2c(S(=O)(=O)O)nc3ccccc32)c1
c. COc1cc(OC)cc(C(=O)NCC2CCCN(C(=O)c3csc(C(C)C)n3)C2)c1
Answer: b. Cc1cccc(OCCn2c(S(=O)(=O)O)nc3ccccc32)c1
