Task: Answer the multiple choice question.
Question: Which drug exhibits a 15.557\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. O=C(Nc1cccnc1)c1cc(-c2cc(Cl)ccc2O)n[nH]1
b. COc1cccc(/C(C)=N/Nc2ccc(S(=O)(=O)N3CCCCC3)cn2)c1
c. O=C(O)CCN1Cc2ccccc2C1=O
Answer: c. O=C(O)CCN1Cc2ccccc2C1=O
