Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.243\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(CCNC(=O)c1ccc(Cl)cc1)NN1C(=O)NC2(CCCCC2)C1=O
b O=C(NCCc1ccc(Cl)cc1)c1cccs1
c Cc1ccccc1Cn1c(=O)n(Cc2ccco2)c(=O)c2ccccc21
d O=[N+]([O-])c1ccc(NC(=S)NCCc2ccc(F)cc2)cc1
Answer: b. O=C(NCCc1ccc(Cl)cc1)c1cccs1
