Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.973\% 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. NS(=O)(=O)c1ccc(NCC2COc3ccccc3O2)c([N+](=O)[O-])c1
b. Cc1c(C(C)(C)C)s/c(=N/S(=O)(=O)c2ccccc2)n1C
c. COCCNC(=S)N(Cc1cccnc1)Cc1ccc(OC)c(OC)c1.O=C(O)C(=O)O
d. CCOC(=O)C1CCCN(Cc2cc(=O)oc3cc(C)ccc23)C1
Answer: a. NS(=O)(=O)c1ccc(NCC2COc3ccccc3O2)c([N+](=O)[O-])c1
