• A. Thin wall for gaseous exchange
• B. Rich PEP carboxylase
• C. High density of chloroplasts
• D. Large intercellular spaces

Answer 1

A) Bundle sheath cells have thick walls to prevent gaseous exchange.
B) Mesophyll cells have PEP carboxylase while bundle sheath cells have RuBisCO.

C) Bundle sheath cells have a large number of chloroplasts.
D) They do not have any intercellular spaces.
So the correct answer is 'High density of chloroplasts'.
