Task: Answer the multiple choice question.
Query: Which drug has a 13.016\% 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) CC1CN=C(NCCc2ccccc2)S1
(b) CCN(N=Nc1cccc([N+](=O)[O-])c1)c1cccc([N+](=O)[O-])c1
(c) Cc1nn(-c2ccccc2)c(C)c1C(=O)OC(C)C(=O)NC1CCCCC1C
(d) COc1ccccc1OCCC(=O)NCc1ccc2c(c1)OCO2
Answer: a. CC1CN=C(NCCc2ccccc2)S1
