Problem statement: Answer the MCQ question.
Query: Which compound has a 4.753\% 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, d, or e without using any additional words.
Options:
a.) COC(=O)C1=Nc2ccccc2/C1=C\c1c(O)n(-c2ccc(OC)cc2)c(=O)[nH]c1=O
b.) Cc1cc2ccc(C)c(C)c2nc1SCC#N
c.) Cc1ccc2nc(N3CCN(S(=O)(=O)c4ccc5c(c4)OCCO5)CC3)c(C#N)cc2c1
d.) O=C(CCS(=O)(=O)c1ccccc1)Nc1ccc2c(c1)OCO2
e.) C=CCN1C(=O)C(CC(=O)Nc2ccccc2)SC1=Nc1ccc(S(N)(=O)=O)cc1
Answer: a. COC(=O)C1=Nc2ccccc2/C1=C\c1c(O)n(-c2ccc(OC)cc2)c(=O)[nH]c1=O
