Task: Answer the MCQ question.
Question: Which drug exhibits a 4.510\% 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: COCCN(CC(=O)Nc1ccccc1C(F)(F)F)C(=O)c1ccc(-n2cccn2)cc1
b: Cc1[nH]c(=O)c(C#N)c(C)c1Cl
c: Cc1ccc(-n2cc(CNCCCn3cccn3)c(-c3cccc(C)c3)n2)cc1
d: Cc1ccn(C)c(=N)c1
e: COc1ccc(C2CC(c3ccc(Br)cc3)=NN2C(=O)CCC(=O)O)cc1OC
Answer: b. Cc1[nH]c(=O)c(C#N)c(C)c1Cl
