Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.552\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a N#C/C=C(/N)c1ccc(Br)cc1
b CCOC(=O)C1CCN(C(=O)COC(=O)c2oc3ccc(OC)cc3c2C)CC1
c O=C(O)c1ccccc1-c1ccccc1C(=O)NCc1cccnc1
d O=C(NC(=S)Nc1ccc(N2CCOCC2)c(Cl)c1)c1cccs1
Answer: a. N#C/C=C(/N)c1ccc(Br)cc1
