Task: Answer the multiple choice question.
Question: Which compound exhibits a 9.126\% 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 Cc1ccc(C)c(N(C(=O)c2csnn2)C(C(=O)NC2CCCCC2)c2ccccn2)c1
b CCCCNC(=O)CNC(=O)c1nn(-c2ccc(OC)c(Cl)c2)c(=O)c2ccccc12
c COC(=O)c1[nH]c2c(c1C)C(=O)CC(c1ccccc1)C2
d Cc1ccccc1NC(=S)N(CCc1c(C)[nH]c2ccc(F)cc12)Cc1ccncc1
Answer: c. COC(=O)c1[nH]c2c(c1C)C(=O)CC(c1ccccc1)C2
