I held the periscope up to the light and was delighted with the many patterns i saw

Answer 1

the best sentence that suits for periscope is sitting behind the tall stone walls, the soldier used a periscope to view the field surrounding the forts.

the reason why I see the answer is that is because scientists don't use parascope to view organisms in the water sample, and we as people don't use Periscope to look at the sky when it's full moon, and when using periscope it don't delights with many patterns, so the answer is actually sitting behind the tall stone walls,the solider use the Periscope to view the field surrounding the forts.

Answer 2

The correct sentence is c) Sitting behind the tall stone walls, the soldier used a periscope to view the field surrounding the fort.

A periscope (a tube with a set of mirrors) is an apparatus with which we can see things on a surface if we are submerged (for example, in a submarine) or if there is a tall obstacle in front of us, like in this example, we can use a periscope to see things which would otherwise be impossible to see.
