Task: Answer the multiple choice question.
Question: Which compound exhibits a 6.171\% 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(CO)N=C1CC(C)(C)CC(=O)/C1=C(/O)CCCN1C(=O)c2ccccc2C1=O
b. CC(=O)c1ccc(NC(=O)c2c(C)nn(-c3ccccc3)c2Cl)cc1
c. COc1ccc(CC(=O)Nc2ccc3nc(C)sc3c2)cc1OC
d. COCCCN=Cc1c(C)[nH]n(-c2ccc(Br)c(C)c2)c1=O
Answer: c. COc1ccc(CC(=O)Nc2ccc3nc(C)sc3c2)cc1OC
