Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 21.537\% 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, d, or e without using any additional words.
Options:
a. CCOc1ccc(S(=O)(=O)N2CCC(C(=O)NCc3ccccn3)CC2)cc1C
b. CC(=O)NC1C(=O)N=C(SCC(=O)NCc2ccccc2)NC1=O
c. CC(=O)c1c(C)[nH]c(C2=NNC(=NC(C)(C)C)SC2)c1C
d. CCN(CC(=O)NC(=O)NCc1ccccc1)Cc1nc2ccccc2c(=O)[nH]1
e. O=C1c2ccncc2C(=O)N1c1cccc(Cl)c1
Answer: c. CC(=O)c1c(C)[nH]c(C2=NNC(=NC(C)(C)C)SC2)c1C
