Task: Answer the multiple-choice question.
Question: Which drug exhibits a 0.929\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CC(CCCC(C)(C)O)CC1C2=C(CCCC2=O)OC2=C1C(=O)CCC2
b. N#CCCn1cc(C(=O)Nc2ccccc2Cl)c(-c2ccc(F)cc2)n1
Answer: a. CC(CCCC(C)(C)O)CC1C2=C(CCCC2=O)OC2=C1C(=O)CCC2
