Task: Answer the multiple-choice question.
Query: Which drug exhibits a 18.076\% 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] COc1ccc(CNc2ccc3c(c2)CCC3)cc1Br
[b] CC1=NN(c2ccccc2)C(=O)/C1=C\c1cc(C)n(C)c1C
[c] CC1(C)CC(=O)C(C=NCc2ccc3c(c2)OCO3)=C(O)C1
Answer: a. COc1ccc(CNc2ccc3c(c2)CCC3)cc1Br
