Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.730\% 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 additional words.
Options:
a) COc1ccccc1N1CCN(Cc2ccc3c(c2)OCO3)CC1
b) COc1ccc(S(=O)(=O)N(C)c2ccc(C(=O)N3CCN(c4ccccc4)CC3)cc2)cc1OC
c) CCN1C(=O)N[C@@H](c2ccccc2)C(C(=O)OC)=C1C
Answer: a. COc1ccccc1N1CCN(Cc2ccc3c(c2)OCO3)CC1
