Problem statement: Answer the multiple-choice question.
Query: Which drug has a 3.775\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: O=c1ccc(/C=C/c2ccccc2)nn1Cc1ccc(Cl)cc1Cl
b: COc1ccc(NS(=O)(=O)c2cn(C)c(=O)n(C)c2=O)c(OC)c1
c: Cc1cccc2cc(CN(Cc3cccs3)C(=S)NCC3CCCO3)c(=O)[nH]c12
d: CC(=O)c1cc(F)c(N2CCN(C(=O)COc3ccc(F)cc3)CC2)cc1C
e: O=c1[nH]c(CN2CCN(c3ccccc3)CC2)nc2scc(-c3ccccc3)c12
Answer: a. O=c1ccc(/C=C/c2ccccc2)nn1Cc1ccc(Cl)cc1Cl
