Task: Answer the multiple choice question.
Query: Which drug has a 4.052\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: c1ccc(OCc2nc3c4c(ncn3n2)-c2ccccc2CC42CCCC2)cc1
b: C=C(C)Cn1c(Sc2nc3ccccc3[nH]2)nc2c1c(=O)[nH]c(=O)n2C
c: O=C(C1CCCCC1)N1CCCc2ccccc21
Answer: a. c1ccc(OCc2nc3c4c(ncn3n2)-c2ccccc2CC42CCCC2)cc1
