Problem statement: Answer the multiple choice question.
Query: Which drug has a 4.850\% 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: CCCC(=O)Nc1cccc(-c2cn3cccnc3n2)c1
b: CCC(NC(=O)Nc1nnc(C(F)(F)F)s1)(C(F)(F)F)C(F)(F)F
c: Cc1ccc(-n2nnnc2SCC(=O)c2c(N)n(CC(C)C)c(=O)n(C)c2=O)cc1
d: c1csc(-c2nc3ccccn3c2NC2CCCCC2)c1
e: Cc1ccc(-c2ccc(/C=N\NC(=O)c3cc4c(ccc5ccccc54)o3)o2)cc1[N+](=O)[O-]
Answer: b. CCC(NC(=O)Nc1nnc(C(F)(F)F)s1)(C(F)(F)F)C(F)(F)F
