Which outcome results when elevated salinity inhibits the Kranz anatomy's function?

A)Suppressed Hatch-Slack CO2 fixation
B)Increased photorespiration efficiency sharply
C)Enhanced Rubisco oxygenase activity heavily
D)Unrestricted stomatal opening continuously

💡 Explanation

Inhibiting Kranz cells leads to the reduced functionality of the Hatch-Slack pathway because proper CO2 concentration is not maintained; therefore, C4 photosynthesis diminishes, inhibiting Rubisco function, rather than other processes less reliant on spatial leaf specialization.
