• C. Intercalary meristem
• D. Primary meristem

Answer 1

The correct option is B Lateral meristem

In the dicotyledons, three types of lateral meristems are present. They are

Fascicular cambium - primary lateral meristem, take part in intra stelar secondary growtrh.

Interfascicular cambium - secondary meristem, take part in intra stelar secondary growth.
