Task: Answer the multiple-choice question.
Query: Which drug has a 4.040\% 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.) CCCN(CC(=O)Nc1ccccc1OC)C(=O)C1CCCC1
b.) O=C(NC1CCCCC1)N1CCN(C2CCCCC2)CC1
c.) O=C(c1ccc(Cn2cc(Br)cn2)cc1)N1CCN(c2ccccc2)CC1
Answer: c. O=C(c1ccc(Cn2cc(Br)cn2)cc1)N1CCN(c2ccccc2)CC1
