Problem statement: Answer the MCQ question.
Question: Which compound has a 4.210\% 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, or c without using any additional words.
Options:
a: C=C(C)CNC(=S)NN=C1c2ccccc2-c2ccccc21
b: O=C(NC1CC2CCCC(C1)N2C(=O)NC1CCCCC1)c1ccc(F)cc1
c: CC(NC(=O)c1ccc(N2CCCC2)c([N+](=O)[O-])c1)c1ccc(S(N)(=O)=O)cc1
Answer: a. C=C(C)CNC(=S)NN=C1c2ccccc2-c2ccccc21
