Task: Answer the multiple choice question.
Query: Which drug has a 10.155\% human ether-à-go-go related gene (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(COc1ccc(Br)cc1Cl)NC(=O)NC1CCCC1
b O=C(CSc1nc2ccc(Cl)cc2[nH]1)c1c[nH]c2ccccc12
c COc1ccc([N+](=O)[O-])cc1NC(=O)C1CCCCC1C(=O)O
d CCN(CC)C(=O)c1cccc2c1C(=O)c1ccccc1-2
Answer: a. O=C(COc1ccc(Br)cc1Cl)NC(=O)NC1CCCC1
