Task: Answer the MCQ question.
Question: Which compound exhibits a 11.666\% 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 other words.
Options:
[a] O=C(c1ccc(S(=O)(=O)Nc2ccccc2Cl)cc1)N1CCOCC1
[b] COCCNC(=O)/C(C#N)=C/c1ccc(O)cc1
[c] COc1ccc(Oc2nnc(-c3ccc(C)cc3)c3ccccc23)cc1
[d] O=C(NC1CN2CCC1CC2)c1ccc(-c2ccc([N+](=O)[O-])cc2)o1
Answer: b. COCCNC(=O)/C(C#N)=C/c1ccc(O)cc1
