Problem statement: Answer the MCQ question.
Question: Which compound exhibits a 7.069\% 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 other words.
Options:
a: COCCNC(=O)C/C(C)=N/NC(=O)C(=O)NC1CCCCC1
b: O=c1[nH]c(CCl)nc2cc(-c3ccc(Cl)cc3)sc12
c: O=C(NC1CCS(=O)(=O)C1)c1ccc2c(c1)OCO2
d: O=C(CSc1nnc(-c2ccc(Cl)cc2)o1)N1CCOCC1
e: COc1ccc(S(=O)(=O)N2CCCC(C(F)(F)F)C2)cc1
Answer: b. O=c1[nH]c(CCl)nc2cc(-c3ccc(Cl)cc3)sc12
