Task: Answer the multiple-choice question.
Question: Which drug has a 17.496\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C(c1ccc(Br)o1)N(Cc1ccccc1)Cc1ccccc1
b: COc1ccccc1[As](=O)(O)CC(O)COc1ccc(Cl)cc1Cl
c: O=C(NC1CCCCC1)c1nc2c(nnn2Cc2ccccc2Cl)c(=O)[nH]1
d: O=C(CSc1nc2ccccc2o1)NC(=O)NCc1ccco1
Answer: c. O=C(NC1CCCCC1)c1nc2c(nnn2Cc2ccccc2Cl)c(=O)[nH]1
