Task: Answer the multiple-choice question.
Query: Which drug has a 1.691\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] Cc1cc(C)n(-c2n[nH]c(=O)c3ccccc23)n1
[b] CCN(Cc1ccccc1)CC(O)COC(c1ccc(OC)cc1)c1ccc(OC)cc1
[c] COc1cc(C2C(C(=O)c3ccc(C)o3)=C(O)C(=O)N2Cc2ccccc2)ccc1O
[d] Cc1cc(C)cc(C(=O)NN2CCOCC2)c1
[e] COc1ccc(S(=O)(=O)c2nnn(-c3ccccc3Cl)c2N)cc1
Answer: c. COc1cc(C2C(C(=O)c3ccc(C)o3)=C(O)C(=O)N2Cc2ccccc2)ccc1O
