Problem statement: Answer the multiple choice question.
Question: Which drug has a 21.692\% 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 other words.
Options:
a: Cc1ccc(-n2cnnn2)c2cccnc12
b: COc1cccc(NC(=O)c2cc([N+](=O)[O-])ccc2NC(=O)CNCC2CCCO2)c1
c: Cc1nc(CCNC(=O)CC2C(=O)NCCN2Cc2ccccc2)nc2c1CCC2
d: O=C(Nc1ccccc1)/C(=C/c1ccc([N+](=O)[O-])cc1)NC(=O)c1ccccc1
e: Cc1ccc(C(=O)NCC(=O)OCC(=O)Nc2ccc3[nH]c(=O)[nH]c3c2)cc1
Answer: c. Cc1nc(CCNC(=O)CC2C(=O)NCCN2Cc2ccccc2)nc2c1CCC2
