Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -2.693\% 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 additional words.
Options:
[a] CNC(=S)N(CCc1c(C)[nH]c2ccc(C)cc12)Cc1ccco1
[b] CSc1nnc(C(C)(C)C)c(=O)n1/N=C/c1ccccc1O
[c] COCCSc1ccccc1C(=O)Nc1ccc2c(c1)OCO2
Answer: a. CNC(=S)N(CCc1c(C)[nH]c2ccc(C)cc12)Cc1ccco1
