Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.402\% 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: COc1cc(NC(=O)CN2C(=O)C(c3ccccc3)=NC23CCCCCC3)cc(OC)c1
b: C#CCn1cnc2c(cnn2-c2ccc(C)c(C)c2)c1=O
c: COc1ccc(Cc2nnc(NS(=O)(=O)c3ccc(Cl)cc3)s2)cc1OC
d: COc1ccc(C(=O)NC(=S)NCC2CCCO2)cc1
Answer: b. C#CCn1cnc2c(cnn2-c2ccc(C)c(C)c2)c1=O
