Task: Answer the multiple-choice question.
Question: Which drug exhibits a 22.284\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COC(C)c1oc2c(C)c3oc(=O)cc(C)c3cc2c1C
[b] O=C(O)Cn1ccnc1
[c] Cc1cccc(-n2c(C)cc(C=C3C(=O)c4ccccc4C3=O)c2C)c1
Answer: c. Cc1cccc(-n2c(C)cc(C=C3C(=O)c4ccccc4C3=O)c2C)c1
