{'nail varnish remover': [0, 0, 1, 0], 'vinegar': [0, 0, 3, 2], 'acetone': [0, 0, 2, 2], 'methyl alcohol': [0, 1, 2, 0], 'benzene': [1, 0, 7, 3]}

The correct answer is option 4 - Acetone. Nail varnish remover generally contains acetone.

Acetone is a clear, colorless liquid that is commonly used as a solvent. It is highly effective in removing nail polish and other substances from the surface of the nails. Acetone has a strong odor and is highly volatile, meaning it evaporates quickly.

Option 1 - Vinegar is incorrect. Vinegar is not commonly found in nail varnish remover. Vinegar is a diluted form of acetic acid and is commonly used in cooking and household cleaning.

Option 2 - Benzene is incorrect. Benzene is a highly toxic chemical and is not used in nail varnish remover due to its harmful effects on human health.

Option 3 - Methyl alcohol is incorrect. Methyl alcohol, also known as methanol, is a toxic and flammable liquid. It is not commonly used in nail varnish remover.

In summary, nail varnish remover generally contains acetone as the active ingredient due to its effectiveness in removing nail polish.
