Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.111\% human ether-à-go-go related gene (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:
[a] COc1ccc(C2(C(=O)Nc3ccc(S(=O)(=O)Nc4nc(C)cc(C)n4)cc3)CCCC2)cc1OC
[b] O=C(NCCc1cccs1)c1cccs1
[c] Cc1ccc(C(=O)Nc2c[nH]c(=O)[nH]c2=O)cc1
Answer: b. O=C(NCCc1cccs1)c1cccs1
