what is the name of the light trapping substance in the leaf
C4 plants have concentric rings of mesophyll cells around vascular bundle sheath in the leaves.
C4
C3 and C4 plants are named after the number of carbon molecules in the first products of their carbon fixation cycles. C3 plants produce 3-phosphoglycerate and C4 plants produce Oxaloacetate.
The C4 plants tend to keep their stomata closed during the day to conserve water.
The plants which live in water are aquatic plants.

Technically, the answer is no because it does not have the anatomical structure of C4 plants. However, it has adaptation similar to C4 plants with regard to carbon dioxide use efficiency. (Ref. Mineral nutrition of higher plants : 2nd edt : pg 140)

Look in your book, page 119.
Since C4 plants need for CO2 is more than C3 plants, doubling the concentration of CO2 will have more positive effect on C4 plants. If CO2 is a limiting factor for photosynthesis, both C3 & C4 plants will have positive effect.
Around 50ppm for C3 plants and around 5ppm for C4 plants.
C4 plants that use the C4 pathway require more ATP and NADPH
The C4 plants tend to keep their stomata closed during the day to conserve water.
c3
The plants which live in water are aquatic plants.
c4 plants have first product of calvin cycle is oxaloacetic acid but in c3 plants is phospfoglyceric acid
