Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.050\% 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 other words.
Options:
[a] O=C(CSc1nc(C2CCCCC2)n(-c2ccccc2)n1)NCC(F)(F)F
[b] Cc1cccc(Cc2c(C)[nH]c(=O)c(C#N)c2C)c1
[c] CCN1CCN(C(=O)C2CCN(S(=O)(=O)c3ccc4c(c3)NC(=O)C(C)S4)CC2)CC1
[d] COc1ccccc1NC(=O)Cn1cnc2c(nc3n2CCCCC3)c1=O
[e] O=c1nc(-c2ccccc2)n(-c2ccccc2)[nH]1
Answer: b. Cc1cccc(Cc2c(C)[nH]c(=O)c(C#N)c2C)c1
