Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 22.817\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 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(Cc1ccc(Cl)cc1)Nc1ccncc1
b) CCCN1CCN(C(=S)Nc2ccc([N+](=O)[O-])cc2)CC1
c) CSCC[C@H](NC(=O)NCCC1=CCCCC1)C(=O)O
d) O=C(/C=C/c1cccc(O)c1)c1cccnc1
Answer: a. O=C(Cc1ccc(Cl)cc1)Nc1ccncc1
