Task: Answer the multiple-choice question.
Question: Which drug exhibits a 15.127\% 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. O=C(Nc1ccc(Br)cc1)N1CCCC(O)C1
b. COc1nc(NS(=O)(=O)c2ccc(C)cc2)nc(C)c1Cl
c. COc1ccc(OC)c(N(CC(=O)Nc2ccc(NC(C)=O)cc2)S(C)(=O)=O)c1
Answer: a. O=C(Nc1ccc(Br)cc1)N1CCCC(O)C1
