Task: Answer the multiple choice question.
Query: Which drug exhibits a 10.326\% 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.) O=C(COc1cccnc1[N+](=O)[O-])NCCc1ccccc1
b.) CCOc1ccc(NC(=O)c2cc3c(C)nc4ccccc4c3o2)cc1
c.) CCC(C)NC(=O)CN1C(=O)NC2(CCOc3ccccc32)C1=O
d.) COc1ccccc1C(=O)NCc1ccco1
Answer: a. O=C(COc1cccnc1[N+](=O)[O-])NCCc1ccccc1
