Task: Answer the multiple-choice question.
Question: Which drug exhibits a 14.976\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CCOc1ccc(N2C(=O)CC(NCCNc3ccc([N+](=O)[O-])cn3)C2=O)cc1
b) CCn1c(SCC(=O)c2c(N)n(C3CC3)c(=O)[nH]c2=O)nc2cc(S(N)(=O)=O)ccc21
c) C=CCn1c(C)cc(C(=O)COC(=O)C2CC(=O)N(CCc3ccc(OC)c(OC)c3)C2)c1C
d) Cc1ccc(NC(=O)c2c(C)nc3ccccn23)cc1C
Answer: b. CCn1c(SCC(=O)c2c(N)n(C3CC3)c(=O)[nH]c2=O)nc2cc(S(N)(=O)=O)ccc21
