Problem statement: Answer the multiple choice question.
Query: Which drug has a -3.070\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a Cn1c(O)c(C=NC2CCCCC2)c(=O)[nH]c1=S
b O=C(CCc1nnc2ccc(N3CCC4(CC3)OCCO4)nn12)N1CCCCC1
c Cc1ccccc1Cn1nc(C)c(NC(=O)c2cc(CC(C)C)on2)c1C
d O=C(c1ccc([N+](=O)[O-])cc1)N1CCc2ccccc2C1
Answer: a. Cn1c(O)c(C=NC2CCCCC2)c(=O)[nH]c1=S
