Task: Answer the multiple choice question.
Question: Which drug exhibits a 15.781\% 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) Cc1ccc(-c2nc3ccccc3nc2NN)cc1
(b) C=Cn1cc[n+](CC(=O)c2ccc(OC)c(OC)c2)c1.[Br-]
(c) O=C(c1ccccc1F)N(Cc1ccc2c(c1)OCO2)Cc1cc2cc3c(cc2n2nnnc12)OCO3
(d) Cn1c(=O)n(CCOc2ccccc2Cl)c2ccccc21
(e) Cc1cc2nc3n(c2cc1C)CC1CC(C(=O)NCCC(C)C)N(C)C31
Answer: a. Cc1ccc(-c2nc3ccccc3nc2NN)cc1
