In the context of plant movements, a mimosa plant (often referred to as Mimosa pudica) exhibits a characteristic response called thigmonasty, which is a rapid movement in response to touch. When the leaves of the mimosa are pinched or touched, they fold and droop, which is a defense mechanism to deter herbivores.
Given your options, the correct answer would be:
It is moving towards touch.
However, the mimosa's movement in response to touch doesn't imply that it is moving towards touch as in seeking it out; rather, it is a reactive response to contact. The main reason for the movement when the leaves are pinched is a rapid change in turgor pressure in the leaf cells.
