The correct answer is option 'C' - Because of the non-profitability of his business.

The Peddler resorted to begging and thievery because his business was not profitable. Let's explore this in detail:

1. Introduction:
- The Peddler was a traveling salesman who sold small household items.
- Despite his efforts, he was unable to make a sufficient income from his sales.

2. Lack of demand:
- The Peddler faced a challenge in finding customers who were interested in buying his products.
- The demand for his goods might have been low due to various factors, such as economic conditions or the availability of similar items in the market.

3. Competition:
- The Peddler might have faced tough competition from other salesmen or local shops.
- If other sellers offered similar products at lower prices or with better marketing strategies, customers would prefer buying from them instead of the Peddler.

4. High expenses and low profits:
- Running a business involves various expenses, such as purchasing inventory, transportation costs, and accommodation expenses for the Peddler.
- If the Peddler's sales were not enough to cover these expenses, it would lead to low profits or even losses.

5. Financial difficulties:
- The Peddler's inability to earn a sufficient income from his business could have resulted in financial difficulties.
- He might have struggled to meet his basic needs, such as food, shelter, and clothing, leading him to resort to begging and thievery as desperate measures to survive.

6. Lack of alternatives:
- The Peddler's decision to resort to begging and thievery could also be influenced by the lack of viable alternatives.
- If he did not possess the necessary skills or resources to pursue other occupations, he might have felt trapped and left with no other option but to engage in illegal activities for survival.

In conclusion, the Peddler resorted to begging and thievery because his business was not profitable. The lack of demand, competition, high expenses, low profits, financial difficulties, and the absence of viable alternatives pushed him to take desperate measures to sustain himself.
