Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.241\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(COC(=O)c1nc(Cl)ccc1Cl)Nc1ccc2[nH]c(=O)[nH]c2c1
(b) CCOc1ccccc1-n1c(SCC(=O)Nc2ccccc2C(=O)O)nc2ccccc2c1=O
(c) O=C(CC1Oc2ccccc2NC1=O)NCc1ccccc1
Answer: c. O=C(CC1Oc2ccccc2NC1=O)NCc1ccccc1
