Task: Answer the multiple choice question.
Query: Which compound has a 15.935\% 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 COc1cccc(SCc2noc(C(=O)NCc3ccccc3)c2C(=O)NCc2ccccc2)c1
b Cl.O=C(OC1CCN(CCCl)CC1)C(c1ccccc1)c1ccccc1
c COc1ccccc1N1CCN(C(=O)C(NS(=O)(=O)c2cccs2)c2ccccc2)CC1
d Cc1cnc(C(=O)Nc2nccs2)cn1
Answer: b. Cl.O=C(OC1CCN(CCCl)CC1)C(c1ccccc1)c1ccccc1
