Task: Answer the multiple choice question.
Question: Which drug has a 7.022\% 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=C1C=C(NCc2ccccc2)CCC1
b. O=C(O)CCC(=O)N1CCOc2ccc(Cl)cc21
c. CC(=O)N1CN(C2CCCC2)Cc2c1sc1c2CCCC1
d. COc1ccc(C(=O)N2CCCC(c3nc(-c4cccs4)no3)C2)cc1OC
Answer: b. O=C(O)CCC(=O)N1CCOc2ccc(Cl)cc21
