Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -2.128\% 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.) CC(C)n1c(N2CCN(C(=O)c3cccs3)CC2)nc2ccccc21
b.) CCN1C(=O)C(CC(=O)Nc2ccccc2)N(Cc2ccccn2)C1=S
c.) CCc1nnc(NC(=O)C2CCCN2C(=O)Nc2ccc(Cl)cc2)s1
Answer: b. CCN1C(=O)C(CC(=O)Nc2ccccc2)N(Cc2ccccn2)C1=S
