Correct option is A
Statement:
"Sale up to 70% on all clothing items in the store and online."
Conclusion I: "All clothing items are 70% off during the sale period."
Analysis: This conclusion is false.
The statement specifies "up to 70%," meaning not all items are 70% off. Some items may have lower discounts.
Conclusion II: "There are some clothing items that are not on sale."
Analysis: This conclusion is false.
The statement explicitly mentions that all clothing items in the store and online are part of the sale. Therefore, there are no clothing items excluded from the sale.
Thus, correct option is (a).
