Task: Answer the multiple choice question.
Query: Which drug has a 18.779\% 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] COC(=O)C1=C(c2ccc(S(C)(=O)=O)cc2)C[C@@H]2CC[C@H]1N2C(=O)N1CCC(C)CC1
[b] COc1cc(/C=C/C(=O)c2c(O)cc(C)oc2=O)cc(OC)c1O
[c] CC1CCCC(C)N1C(=O)CN1C(=O)c2ccccc2S1(=O)=O
[d] COCCCNC(=O)CN1C(=O)COc2ccc(S(=O)(=O)N3CC(C)CC(C)C3)cc21
Answer: b. COc1cc(/C=C/C(=O)c2c(O)cc(C)oc2=O)cc(OC)c1O
