Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.913\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CC1(C)CC(=O)C(C=NCCN2CCN(C3CC(=O)N(c4ccc(Br)cc4)C3=O)CC2)=C(O)C1
b. COc1cccc(C(=O)COc2ccc3c(C)c(Cc4ccccc4)c(=O)oc3c2)c1
Answer: a. CC1(C)CC(=O)C(C=NCCN2CCN(C3CC(=O)N(c4ccc(Br)cc4)C3=O)CC2)=C(O)C1
