Problem statement: Answer the MCQ question.
Question: Which drug exhibits a -16.724% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCOC(=O)C1=C(COC(=O)/C=C/c2ccc(SC)cc2)NC(=O)NC1C
b: CCOC(=O)c1ccc(NS(=O)(=O)c2c(C)n(C)c(=O)n(C)c2=O)cc1
c: C/C(=N\NC(N)=S)c1cccnc1
d: S=C=Nc1ccccn1
Answer: d. S=C=Nc1ccccn1
