Analyze the Statement: The core statement is "Most of the wrist watches in this shop are expensive." The keyword here is "Most", which signifies a majority (more than 50%) but not all.

Understanding the Implications of "Most"

• If most watches are expensive, it means a portion of watches are not expensive.
• This non-expensive portion could include watches that are moderately priced or cheap.

Evaluating the Options

• Option 1: "All the ladies wrist watches are expensive." This option introduces "ladies wrist watches," a specific category not mentioned in the original statement. We cannot make this conclusion.
• Option 2: "None of the wrist watches are cheap." This is incorrect because if some watches are not expensive, they might be cheap. "None" is too strong a claim.
• Option 3: "There are cheap wrist watches also in the shop." This aligns with the implication that if most are expensive, then some are not expensive, and these could potentially be cheap.
• Option 4: "All the wrist watches in shop are expensive." This directly contradicts the word "Most". "Most" explicitly implies that not all watches fall into the expensive category.

Conclusion

Based on the analysis, the most logical conclusion derivable from "Most wrist watches are expensive" is that there exists a possibility, or even likelihood, that some watches are not expensive, potentially including cheap ones.

Therefore, the conclusion that can be drawn is: There are cheap wrist watches also in the shop.
