Task: Answer the multiple choice question.
Question: Which compound exhibits a -73.442% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCOC(=O)C1CCN(c2c(N3CCN(Cc4ccccc4)CC3)c(=O)c2=O)CC1
b: Cc1cc(C)cc(NC(=O)CN2CCN(C(=O)C3CCCO3)CC2)c1
c: Cc1nc(NC(=O)c2cccnc2Cl)sc1C
d: CCc1c(C)nc2cc(-c3cccc(Br)c3)[nH]n2c1=O
e: O=C(/C=C\c1cn(-c2ccccc2)nc1-c1cccs1)N1CCOCC1
Answer: a. CCOC(=O)C1CCN(c2c(N3CCN(Cc4ccccc4)CC3)c(=O)c2=O)CC1
