Task: Answer the MCQ question.
Question: Which compound exhibits a 4.654\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) COC(=O)CN1C(c2ccc(OC)cc2)=Nc2ccc(Cl)cc2C1c1ccccc1
b) COc1ccccc1C(CNC(=O)CNC(=O)c1ccc(C)c(C)c1)N1CCCC1
c) O=C(Nc1cccc(S(=O)(=O)NC2=NCCC2)c1)c1cc(Cl)ccc1[N+](=O)[O-]
d) Cc1ccc(NC(N)=S)cc1
Answer: a. COC(=O)CN1C(c2ccc(OC)cc2)=Nc2ccc(Cl)cc2C1c1ccccc1
