Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.512\% 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(Nc1ccccc1)c1ccc(NCc2cccnc2)c(S(=O)(=O)N2CCOCC2)c1
[b] CCCN1C(=O)N(C)C(N(O)C(=O)NC)C1(C)C
[c] CCN(CC)S(=O)(=O)c1ccc2[nH]cc(C(=O)NCCN3CCCCCC3)c(=O)c2c1
[d] COc1cc(/C=N/NP(=S)(c2ccccc2)c2ccccc2)ccc1O
Answer: a. O=C(Nc1ccccc1)c1ccc(NCc2cccnc2)c(S(=O)(=O)N2CCOCC2)c1
