Problem statement: Answer the MCQ question.
Question: Which compound exhibits a 6.870\% 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.) O=C1COC(c2ccccc2)=CN1Cc1ccccc1
b.) CC(=O)c1cccc(N(C(=O)c2ccco2)C(C(=O)NC2CCCC2)c2ccc(N3CCOCC3)cc2)c1
c.) COc1ccc(NC(=O)c2ccc(-c3ccccc3)cc2)cc1S(=O)(=O)N1CCOCC1
d.) CC1=CCC2(CO)COC(c3ccccc3O)C1C2
Answer: a. O=C1COC(c2ccccc2)=CN1Cc1ccccc1
