{'specialized conducting tissue': [0, 0, 0, 1], 'plants': [11, 0, 4, 4], 'other substances': [1, 0, 0, 2], 'transport': [0, 0, 0, 1], 'water': [65, 15, 80, 129], 'fern': [2, 0, 0, 4], 'marchantia': [0, 0, 0, 1], 'marsilea': [0, 0, 0, 1]}

The correct answer is option 1, which is Marchantia. Marchantia is a type of liverwort, which is a non-vascular plant. Non-vascular plants do not possess specialized conducting tissues like xylem and phloem, which are responsible for the transport of water and other substances in plants.

Option 2, Marsilea, is a type of fern. Ferns are vascular plants and possess specialized conducting tissues for the transport of water and other substances. Therefore, option 2 is not the correct answer.

Option 3, Cycas, is a type of gymnosperm. Gymnosperms are also vascular plants and have specialized conducting tissues. Therefore, option 3 is not the correct answer.

Option 4, Fern, is a vascular plant and possesses specialized conducting tissues. Ferns have xylem and phloem that help in the transportation of water and other substances. Therefore, option 4 is not the correct answer.

Therefore, the correct answer is option 1, Marchantia.
