Task: Answer the multiple choice question.
Question: Which compound exhibits a 1.869\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) O=C(COc1cccc(Br)c1)NN=C1c2ccccc2-c2ccccc21
b) O=C(COC(=O)c1cc(Br)ccc1O)Nc1cccnc1Cl
c) N#C/C(=C\c1ccc2c(c1)OCO2)C(=O)N1CCOCC1
d) Nc1ccccc1C(=O)N1CCC(O)(c2ccc(Cl)cc2)CC1
e) COc1ccc(OC)c(-c2nnc(SCC(=O)N3CCOCC3)o2)c1
Answer: a. O=C(COc1cccc(Br)c1)NN=C1c2ccccc2-c2ccccc21
