B. Stamp Coupling

C. Control Coupling

D. Content Coupling

---

Ans: B

Description:

Coupling:

It is represent as dependency.

Data Coupling:

This coupling occurs when modules share data through parameters.

Content Coupling:

This Coupling occurs  when one module modifies the internal working of another module.

Common Coupling:

This coupling occurs when two module share same global data (through global variable).

Stamp or Data Structured Coupling:

This coupling occurs when modules share a composite data-structure and use only part of it.

Control Coupling:

One module controlling the flow of another module by passing information on what to do.
