Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.915\% 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, or c without using any additional words.
Options:
(a) O=C(CNc1ccccc1)N/N=C/c1ccc2c(c1)OCCO2
(b) CN(Cc1ccccc1)C(=O)COC(=O)c1ccc2ccccc2n1
(c) COc1cc2c(cc1OC)C1Cc3c(cnc4c(-c5ccc(F)cc5)cnn34)C(=O)N1CC2
Answer: b. CN(Cc1ccccc1)C(=O)COC(=O)c1ccc2ccccc2n1
