Task: Answer the multiple-choice question.
Query: Which compound exhibits a 2.886\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCN(CC)CCCN1C(=O)C(O)=C(C(=O)c2ccco2)C1c1ccc(OC(C)C)cc1
b: O=C(O)C(=O)O.c1cc2c(cc1CN1CCN(C3CCCCCC3)CC1)OCO2
c: Cc1ccc(CN2CCN(Cc3cccc4nccnc34)CC2CCO)cc1
d: CCCN1C2CCCC1CC(NC(=O)c1cccc(Cl)c1)C2
e: O=C(CNC(=O)c1cccc(Br)c1)N/N=C/c1cccnc1
Answer: a. CCN(CC)CCCN1C(=O)C(O)=C(C(=O)c2ccco2)C1c1ccc(OC(C)C)cc1
