Task: Answer the multiple choice question.
Query: Which drug has a 13.879\% 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.) Cl.O=C(Nc1ccccc1)N1CCNCC1
b.) Cc1cc(C)nc(SCc2ccc(C(=O)N/N=C/c3ccccn3)cc2)n1
c.) Cc1cc(C(=O)N2CCCC(N3CCN(c4cccc(Cl)c4)CC3)C2)no1
d.) C/C(Cn1cnc([N+](=O)[O-])n1)=N/NC(=O)COc1ccccc1Cl
Answer: a. Cl.O=C(Nc1ccccc1)N1CCNCC1
