Task: Answer the multiple-choice question.
Query: Which drug has a 15.742\% 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 CC[C@H](C)[C@@H]1NC(=O)c2cc([N+](=O)[O-])cc(I)c2NCC[C@@H](C(N)=O)NC(=O)[C@H](CCCN=C(N)N)NC1=O
b Cc1nn(C)cc1S(=O)(=O)Nc1ccc2c(c1)OCCO2
c O=C1N(Nc2ccccc2)C(c2ccc(Br)cc2)C12CCCCC2
d Cc1ccc(S(=O)(=O)N(CC(=O)N2CCOCC2)C2CCCCC2)cc1
Answer: c. O=C1N(Nc2ccccc2)C(c2ccc(Br)cc2)C12CCCCC2
