Plants that grow in marshy regions frequently have root adaptations for respiration. Waterlogged or saturated soils in marshy places might contribute to reduced oxygen availability in the root zone. Plants in marshy places evolve specialised root adaptations that improve oxygen uptake from the air to meet this issue.

The growth of pneumatophores or airborne roots is a common root adaptation for breathing in swampy regions. Pneumatophores are erect, spongy structures that protrude above the water's surface and allow gas exchange between submerged roots and the atmosphere, so promoting respiration. Despite the soggy environment, these specialised roots assist plants in marshy locations in obtaining the essential oxygen for metabolic processes.

Therefore, the correct option is Option 2) Modification for respiration.
