Task: Answer the multiple choice question.
Query: Which drug exhibits a 30.025\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] CCOC(=O)C(CCCOc1cccc(CC)c1)C(=O)OCC
[b] O=C(O)/C=C/C(=O)NCCc1ccccc1
[c] Cn1c(=O)[nH]c(=O)c2c1nc(CN1CCN(c3cccc(Cl)c3)CC1)n2CCN1CCOCC1
[d] CCOC(=O)/C=C/C(=O)Nc1ccc(S(=O)(=O)N2CCCCCC2)cc1
[e] O=C(CCS(=O)(=O)c1ccccc1)Nc1ccc2c(c1)OCO2
Answer: b. O=C(O)/C=C/C(=O)NCCc1ccccc1
