Task: Answer the multiple-choice question.
Query: Which compound exhibits a 4.237\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. CCOC(=O)C1=C(C)OC(N)=C(C#N)C1c1cccc(C)c1
b. N#Cc1cccc(Oc2ccc(-c3cnc4ccccc4n3)cc2)c1C#N
c. COc1ccc(CNC(=O)CCCCCNC(=O)N2CCn3c2nc2ccccc23)cc1
d. CCC(CC)NC(=O)/C=C/c1cccc([N+](=O)[O-])c1
e. O=C(COC(=O)/C=C/c1ccc(F)cc1)NCc1cccs1
Answer: b. N#Cc1cccc(Oc2ccc(-c3cnc4ccccc4n3)cc2)c1C#N
