AThe silent film era ✓ Correct

BVideo advertisements

CTelevision network system

DThe advent of computers

Correct answer: (A) The silent film era

Explanation

The Vitascope, an early film projector of the 1890s, introduced the silent film era by showing moving pictures to audiences.

Video advertisements came much later with television and commercial broadcasting.

A television network system belongs to a far later stage of broadcast technology.

The advent of computers is unrelated to the Vitascope, which was a mechanical projector.

The Vitascope was promoted by Thomas Edison in 1896.

Silent films relied on live music and title cards since synchronised sound came later.
