Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 8.160\% 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 additional words.
Options:
[a] CC1C(C#N)=C(N)OC2=C1C(=O)CC(c1ccccc1)C2
[b] C/C(=N/NC(=O)c1ccoc1C)c1ccc(NC(=O)c2ccncc2)cc1
[c] CCC1(COC(=O)Nc2cccc(Cl)c2)COC1
[d] COc1ccc(S(=O)(=O)Nc2cc(C)on2)cc1OC
Answer: a. CC1C(C#N)=C(N)OC2=C1C(=O)CC(c1ccccc1)C2
