Task: Answer the multiple choice question.
Query: Which drug has a 3.649\% 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.) O=C(COC(=O)c1ccc2[nH]c3c(c2c1)CCCC3)Nc1ccccc1Cl
b.) CNc1ccc(/C=C(\C#N)C(=O)Nc2ccccn2)cc1[N+](=O)[O-]
c.) CCCCN(C(=O)c1ccccc1Br)C1CCS(=O)(=O)C1
d.) CC(=O)c1c(C)nc(Nc2nc(C)c3cc(C)ccc3n2)nc1C
Answer: c. CCCCN(C(=O)c1ccccc1Br)C1CCS(=O)(=O)C1
