The construction is aqueducts
The answers that apply are:
1), 2) , 3), 4)
Let's look into them one by one:
1)It is absorbed by Earth.
- Earth is indeed a material that will absorb solar radiation, this is one of the reason why we have a different temperature in the morning and at night.
2)It is reflected by clouds.
- Cloud can reflect solar radiation as it is made up of water particles which can reflect the solar radiation back. This is why in a foggy day the sunlight is dimmer.
3)It is reflected by glacial ice.
-Glacial ice can reflect solar radiation. As glacial ice is smooth and light in colour,much solar radiation that was on the glacier is reflected, this is one of the reason how the North Pole and South Pole are cold all year.
4)It is condensed into visible light.
Solar radiation can light up the area depending on it's intensity, the more intense the radiation is,the brighter it will be.
5) is amplified by water molecules.
Although water molecules can keep the radiation as it has a high specific latent heat, it does not amplify the solar radiation.
Hope it helps!

Answer:
Option (4)
Explanation:
Here, Speed of light= 
Km/sec
Distance= 
Km
We know that,
=500 sec
=8 minutes 20 sec
Hence, the correct answer is option (4) i.e 8 minutes.
