{'nucleus': [1, 0, 1, 0], 'nucleosome': [1, 0, 0, 1], 'nucleoplasm': [1, 0, 0, 1], 'cytoplasm': [2, 0, 0, 5], 'cell': [14, 0, 7, 16], 'liquid': [0, 0, 0, 1], 'protoplasm': [2, 0, 0, 2]}

The correct answer is option 3 - Nucleoplasm. The nucleus of a cell contains a viscous liquid called nucleoplasm. Nucleoplasm is a gel-like substance that fills the space within the nucleus and surrounds the nucleolus and chromatin. It is a complex mixture of water, ions, enzymes, proteins, and other biomolecules.

Option 1 - Cytoplasm, refers to the fluid and organelles outside the nucleus but within the cell. It is not contained inside the nucleus.

Option 2 - Protoplasm, refers to the living matter of a cell, which includes both the cytoplasm and nucleus. While nucleoplasm is part of the protoplasm, it specifically refers to the liquid inside the nucleus.

Option 4 - Nucleosome, on the other hand, refers to a structural unit of DNA and histone proteins in the chromatin, which is found inside the nucleus but is not a liquid.

Therefore, the correct answer is option 3 - Nucleoplasm, as it is the specific liquid contained inside the nucleus of a cell.
