Option A, Connective tissue

Explanation:

In the form of blood and lymph, connective tissues are fluid in nature. The cells move in and around this  liquid extracellular matrix.

In the form of bone, connective tissues are solid in nature as they have a solid calcium matrix for support.

In the form of protein collagen, connective tissues are semi-solid in nature as they are  flexible and strong

hence, connective tissue can be liquid, solid, or semi-solid.
