Problem statement: Answer the multiple choice question.
Question: Which drug has a 3.381\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: Cl.O=C(NCCN1CCCC1)c1ccc(Br)cc1
b: N#Cc1ccc(N2CCCC2C(=O)O)c([N+](=O)[O-])c1
c: CC1CCCCN1C(=O)CCNS(=O)(=O)c1ccc2c(c1)c(=O)n(C)c(=O)n2C
d: O=C(Nc1nc2ccccc2s1)C1CCN(C(=O)c2ccco2)CC1
Answer: a. Cl.O=C(NCCN1CCCC1)c1ccc(Br)cc1
