Task: Answer the multiple choice question.
Query: Which drug has a 12.404\% 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] CC(=O)N/C(N)=N/c1nc2cc([N+](=O)[O-])ccc2o1
[b] CC(=NCCCn1ccnc1)c1c(-c2ccccc2)[nH]n(-c2nc3ccccc3s2)c1=O
[c] O=C(Nc1ccccc1)N1CCSc2ccccc21
[d] O=S(=O)(NCc1cn2ccsc2n1)c1ccc2c(c1)OCCO2
Answer: a. CC(=O)N/C(N)=N/c1nc2cc([N+](=O)[O-])ccc2o1
