Task: Answer the multiple choice question.
Question: Which drug exhibits a -8.763% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(Nc1cccc(N=Cc2cc(Br)cc(Br)c2O)c1)c1ccco1
b COc1ccc(NC(=O)COC(=O)C2CC(=O)N(c3ccc(OC(C)C)cc3)C2)cc1
c O=C(Nc1cccc(C(F)(F)F)c1)Nn1cnnc1
d COC(=O)[C@H](C)NC(=O)Nc1cc(OC)ccc1OC
Answer: d. COC(=O)[C@H](C)NC(=O)Nc1cc(OC)ccc1OC
