Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -2.759% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=c1c2ccccc2[nH]c2ccc(O)cc12
b: CCCc1nc(SCC(N)=O)[nH]c(=O)c1CC
c: Cc1ccccc1NC(=O)c1c(-c2ccccc2)csc1NC(=O)CC(C)C
Answer: a. O=c1c2ccccc2[nH]c2ccc(O)cc12
