B Correct answer
Explanation

Lateral meristems (vascular cambium and cork cambium) are responsible for secondary growth, which increases the girth/thickness of stems and roots. Apical meristem causes primary growth (length increase). Intercalary meristem causes growth at nodes (seen in grasses). Only lateral meristem produces secondary growth.
