Problem statement: Answer the multiple-choice question.
Query: Which drug has a -3.583\% 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: COc1cc(S(=O)(=O)N2CCN(C)CC2)c(OC)cc1Br
b: Cc1cc(C(=O)CSc2nnc(-c3ccccc3)n2C)c(C)n1C
c: Clc1ccccc1/C=C/c1ccnc2ccccc12
Answer: a. COc1cc(S(=O)(=O)N2CCN(C)CC2)c(OC)cc1Br
