Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.003\% 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) COc1ccc2cc(C3NC(=O)c4ccccc4N3)c(Cl)nc2c1
b) COc1cc(Cl)c(C)cc1NC(=O)COC(=O)C1=COCCO1
c) COc1ccc(CNC(=O)C(C)NS(=O)(=O)c2ccc(C)cc2)cc1
d) CCCCN1CC[C@H]2C=CC[C@@H](C(=O)NCc3ccc(OC)cc3)[C@H]2C1=O
Answer: d. CCCCN1CC[C@H]2C=CC[C@@H](C(=O)NCc3ccc(OC)cc3)[C@H]2C1=O
