Task: Answer the multiple choice question.
Query: Which drug has a 3.316\% 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(CCC(=O)Nc1ccc(Br)cc1)N/N=C/c1ccccc1O
b) COc1ccc(C2=CC(=O)CC(C)(C)C2)cc1
c) COc1ccccc1/C=C1\SC(=S)N(CCC(=O)Nc2nnc(C)s2)C1=O
d) Nc1nc(OCC2CCCCC2)c2[nH]cnc2n1
Answer: d. Nc1nc(OCC2CCCCC2)c2[nH]cnc2n1
