Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 3.653\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=C(Nc1cc([N+](=O)[O-])ccc1C(=O)Nc1cccnc1)c1ccccc1
[b] Cc1nc(N2CCN(c3ccccc3)CC2)[nH]c(=O)c1C
[c] C=CCOc1c(CNc2ccc(S(N)(=O)=O)cc2)cccc1OC
Answer: b. Cc1nc(N2CCN(c3ccccc3)CC2)[nH]c(=O)c1C
