Which of the following is an important hygiene practice for your nails?
a.
polish and paint
b.
regular trimming
c.
moisturizing
d.
periodic removal of entire nail

Explanation:

Among these options, regular trimming is an important hygiene practice, other options are not.

Polish and paint are not hygiene practices by themselves. Moisturising is important, but it's not applied on nails, but on the skin, so it's a skin hygiene practice. At last and the worst option, by removing your entire nail you only will get a huge pain, and having no nail anymore.
