Task: Answer the multiple-choice question.
Query: Which drug has a 4.233\% 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(CSCc1ccc(Br)cc1)NC1CC1
b. CC1=C(C(=O)OC2CCCC2)C(c2coc3ccccc3c2=O)C2=C(CC(C)(C)CC2=O)N1
c. COc1cccc(OC)c1C(=O)Nc1ccnn1C
d. COc1ccc(-c2cc(C(=O)Nc3c(Cl)cc(Cl)cc3Cl)c3ccccc3n2)cc1OC
Answer: d. COc1ccc(-c2cc(C(=O)Nc3c(Cl)cc(Cl)cc3Cl)c3ccccc3n2)cc1OC
