Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.299\% human ether-à-go-go related gene (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 additional words.
Options:
a COC(=O)c1nn(-c2ccccc2)ccc1=O
b O=C(COC(=O)CCN1C(=O)c2ccccc2C1=O)Nc1ccc(S(=O)(=O)N2CCCC2)cc1
c Nc1ccccc1[As](=O)(O)c1ccccc1
d COc1cccc2sc(N(CCCN(C)C)C(=O)C(c3ccccc3)c3ccccc3)nc12.Cl
Answer: c. Nc1ccccc1[As](=O)(O)c1ccccc1
