Statements about the effect of ${\mathrm{CO}}_2$ concentration, temperature and light intensity on the rate of photosynthesis in $\mathrm{C}3$ and $\mathrm{C}4$ plants are given. Based on the statements the correct option is
i) At high ${\mathrm{CO}}_2$ concentrations, $40°\mathrm{C}$ and saturated light, the photosynthetic rates of $\mathrm{C}3$ and $\mathrm{C}4$ plants are similar.
ii) $\mathrm{C}4$ plants do not reach saturation levels even at $10\%$ of the full intensity of sunlight.
iii) At twice the levels of ${\mathrm{CO}}_2$ concentration $(~700\mathrm{ppm})$, the net photosynthesis in $\mathrm{C}3$ plants is higher than that of $\mathrm{C}4$plants.
iv) The net CO₂ uptake in a C3 shade plant is equivalent to C4 plant under light saturation conditions.
