Task: Answer the multiple choice question.
Query: Which drug exhibits a -3.719\% 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(CCNC(=O)c1ccc(Br)cc1)OCc1ccccc1Cl
b. CN(C)c1ccc(/C=N\NC(=O)c2ccc(Cn3cc(Cl)cn3)cc2)cc1
c. Nc1ccc(C(=O)OCc2nc3ccccc3s2)cc1
Answer: a. O=C(CCNC(=O)c1ccc(Br)cc1)OCc1ccccc1Cl
