Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.

Statement I:Flat plate collectors are an example of the simplest and most economic solar collectors.

Statement II:Some of the solar concentrating collectors essentially use flat plate collectors.

ABoth Statement I and Statement II are true ✓ Correct

BBoth Statement I and Statement II are false

CStatement I is true but Statement II is false

DStatement I is false but Statement II is true

Correct answer: (A) Both Statement I and Statement II are true

Explanation

Flat plate collectors are indeed among the simplest and most economical solar collectors, so Statement 1 holds.

They use a flat absorbing surface under glazing to capture sunlight without moving parts.

Statement 2 is also acceptable because some concentrating arrangements build on flat plate absorbers.

Certain low-concentration designs place reflectors around a flat plate to boost its input.

Both descriptions therefore stand together.

Flat plate collectors are widely used for domestic water heating in moderate climates.
