Read the given passage. P is a modified underground stem and is an energy giving food. Q is a root that stores food and gets swollen. Nutrient present in Q keeps eyes and skin healthy. R and S are edible seeds. Nutrient in R gets stored in the body and keeps the body warm, while nutrient in S helps in growth and repair of body. T is edible leaf, the nutrient of which helps in formation of blood and its deficiency affects blood clotting. Which of the following statements hold true regarding it?
(i) P could be potato and the deficiency of main nutrient present in it causes kwashiorkor.
(ii) Q could be carrot which contains vitamin A.
(iii) R could be groundnut that majorly yields oil.
(iv) S could be rajma or gram which is rich in fat.
(v) T could be spinach with main nutrients iron and vitamin K.

In the figure shown, PQRS is a rectangular smooth tube kept fixed in a vertical plane. A particle is projected from point P to reach point R with same speed for both the paths PSR and PQR. At the corners Q and S velocity changes its direction by 90° without any change of its magnitude. If time taken for the paths PQR and PSR are t₁ and t₂ respectively, then (given l > b)
