Task: Answer the MCQ question.
Query: Which drug exhibits a -12.972\% 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) COc1cc(OC)nc(S(C)(=O)=O)n1
(b) COc1ccccc1NC(C)C(=O)N/N=C/c1ccccc1OCc1cccc(Br)c1
(c) Cc1nnsc1C(=O)Nc1cc(Cl)ccc1Cl
(d) COc1ccc(/C=N/OC/C(O)=C(\C#N)c2nc3ccccc3[nH]2)cc1
Answer: d. COc1ccc(/C=N/OC/C(O)=C(\C#N)c2nc3ccccc3[nH]2)cc1
