Detailed Solution

Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).

Assertion (A): "Each skeletal muscle fibre is a syncytium."

This statement is correct. A syncytium is a multinucleated cell formed by the fusion of several cells. Skeletal muscle fibers are formed by the fusion of many myoblasts during development, resulting in a multinucleated structure.

Reason (R): "Sarcoplasm of muscle fibre contains many nuclei."

This statement is also correct. The sarcoplasm of a skeletal muscle fiber does contain multiple nuclei, reflecting the multinucleated nature of these cells.
