Task: Answer the multiple-choice question.
Query: Which compound has a 21.346\% 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 other words.
Options:
a.) CCC(C)NC(=O)Nc1ccccc1C
b.) O=C(CN(Cc1ccco1)C(=O)CNS(=O)(=O)c1ccc(F)cc1)NCc1ccc(F)cc1
c.) O=C1C2CC=C(Cl)CC2C(=O)N1c1ncn[nH]1
d.) CCOC(=O)CCCNC(=O)CCNC(=O)c1ccc(OC)cc1
Answer: c. O=C1C2CC=C(Cl)CC2C(=O)N1c1ncn[nH]1
