The correct answer is option 'D' - Because he had no home.

Explanation:
The peddler had to take shelter because he had no home. Let's dive into the details to understand why he found himself in this situation.

1. Introduction:
The peddler is a wandering salesman who travels from place to place to sell his goods. He leads a nomadic lifestyle, which means he doesn't have a permanent residence.

2. Background of the peddler:
The peddler's life is marked by constant movement and uncertainty. He carries his wares on his back and relies on the sales he makes to sustain himself. As he travels from village to village, he searches for customers who might be interested in purchasing his goods.

3. Lack of shelter:
Since the peddler doesn't have a home, he is always in search of a place to stay overnight. Without a proper shelter, he is exposed to the elements and vulnerable to various risks such as bad weather, theft, and physical harm. Therefore, finding shelter becomes a necessity for his survival and well-being.

4. Seeking refuge:
In the absence of a home, the peddler seeks temporary shelter wherever he can find it. He might take refuge in abandoned houses, barns, or even open spaces like caves and trees. These temporary shelters provide him with some protection and a place to rest until he continues his journey.

5. Homelessness as a recurring theme:
The theme of homelessness is prevalent in literature and often serves as a reflection of the character's circumstances and struggles. In the case of the peddler, his lack of a home symbolizes his rootlessness and the transitory nature of his existence.

In conclusion, the peddler had to take shelter because he had no home. This lack of a permanent residence forces him to seek temporary refuge wherever he can find it, highlighting the challenges and uncertainties of his nomadic lifestyle.
