The correct answer is

By storing them in vacuoles or excreting through falling leaves and resins

Plants do not have dedicated excretory organs, so they handle wastes in several ways: many waste products are stored in cell vacuoles or as gums, resins and crystals, and a large amount is removed when old leaves and bark fall off the plant.

Plants also release some wastes into the surrounding soil through their roots, and gaseous wastes through stomata, but the key point is storage and shedding rather than a special organ.

"Through root hairs only" is wrong because root hairs mainly absorb water and minerals; excretion is not limited to them.

"Converting all wastes into oxygen and carbon dioxide" is wrong because most plant wastes are organic compounds that are not turned wholesale into these gases.

Nephrons are filtering units of the animal kidney; plants have no nephrons.

Hence, plants excrete by storing wastes in vacuoles or removing them through falling leaves and resins.
