Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.026\% 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(Nc1nccs1)c1cc([N+](=O)[O-])ccc1Cl
b C=CCn1c(=NC(=O)C2CCCCC2)sc2cc(NC(C)=O)ccc21
c COc1ccc(NC(=S)NC(NC(=O)c2ccccc2Cl)C(Cl)(Cl)Cl)c([N+](=O)[O-])c1
d CCOc1ccc(/C=N/NC(=O)c2nnn(-c3nonc3N)c2CN2CCC(C)CC2)cc1
Answer: b. C=CCn1c(=NC(=O)C2CCCCC2)sc2cc(NC(C)=O)ccc21
