Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 21.052% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1cc(C(C)=O)ccc1Oc1cnccn1
b Cc1csc(NC(=O)c2cccc([N+](=O)[O-])c2C(=O)O)n1
c CCN(CC)S(=O)(=O)c1cccc(-c2nnc(SC(C)C(=O)NCCC3=CCCCC3)o2)c1
d Cc1cc2c(cc1S(=O)(=O)NCc1ccccc1)NC(=O)CO2
Answer: a. COc1cc(C(C)=O)ccc1Oc1cnccn1
