Task: Answer the multiple choice question.
Question: Which drug has a 20.076% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) COc1ccc(NC(=O)c2cc3ccccc3o2)cc1OC
b.) CC(=O)Nc1cccc(C(=O)Nc2nc(C)cs2)c1
c.) CCCCC(=O)N=c1sc2c(OC)ccc(OC)c2n1C
d.) CN1CCC(N(C)CC(=O)Nc2cccc(Oc3ccccc3)c2)CC1.O=C(O)C(=O)O
e.) COc1ccc(CCNC(=O)Cc2cc(OCc3ccccc3)c(OC)cc2[N+](=O)[O-])cc1OC
Answer: c. CCCCC(=O)N=c1sc2c(OC)ccc(OC)c2n1C
