Task: Answer the multiple-choice question.
Question: Which drug exhibits a 1.612\% 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] C=CCn1c(/N=C/c2ccc(N(C)C)cc2)nc2ccccc21
[b] COc1ccc(/C=N/Nc2nc(N)cc(Cl)n2)cc1OC
[c] CNS(=O)(=O)c1cccc(C(=O)OCc2csc(-c3ccccc3)n2)c1
[d] COc1cc(/C=C/C(=O)Nc2cccnc2)cc(OC)c1OC
Answer: a. C=CCn1c(/N=C/c2ccc(N(C)C)cc2)nc2ccccc21
