- 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 — Both statements are true, so the answer is that both Statement I and Statement II are true.
Explanation
★Both statements are true, so the answer is that both Statement I and Statement II are true.
★A flat plate collector is the most common non-concentrating solar collector.
★It is simple and economical for heating water and buildings, so statement I is true.
★Concentrating collectors gather solar radiation over a larger area.
★Some of these concentrating collectors are built around flat plate collectors.
★So statement II is also true.
