Task: Answer the multiple choice question.
Question: Which compound has a 11.633\% 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) O=C(CN1CCOCC1)N1c2ccccc2Sc2ccccc21
b) CC1=C(C)CC(C(=O)NNC(=O)c2cccc(Cl)c2)C(C(=O)O)C1
c) CCNc1ccc(S(=O)(=O)N2CCCCC2)cn1
d) O=C(c1ccc(Cl)cc1)c1cnc2ccccn12
Answer: a. O=C(CN1CCOCC1)N1c2ccccc2Sc2ccccc21
