Task: Answer the multiple choice question.
Query: Which drug has a 15.634\% 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, or d without using any additional words.
Options:
(a) Cc1nc(Nc2ccccc2Cl)sc1C(=O)Nc1ccccc1
(b) O=C(NCC(F)(F)F)Nc1ncccn1
(c) CCN1CCN(c2c(/C=C3\SC(=S)N(Cc4ccco4)C3=O)c(C)c(C#N)c(=O)n2C)CC1
(d) O=c1c(-c2nc3ccccc3s2)cccn1Cc1ccc(Cl)cc1
Answer: b. O=C(NCC(F)(F)F)Nc1ncccn1
