**From Statement(1) ALONE** we can deduce that 3000/4=750 wool jackets but we are __DO NOT KNOW__ if the remaining 250 jackets __can__ be manufactured by the 2000 pounds of cotton.(Irrespective of if the manufacturer intends to make cotton only jackets. So the answer to the question stem can be YES/NO.(Thus, insufficient)

**From Statement(2) ALONE** we can deduce that 333 cotton jackets can be manufactured but we __DO NOT KNOW__ if the remaining 667 jackets __can__ be manufactured by the 3000 pounds of wool.

So the answer to the question stem can be YES/NO.(Thus, insufficient)

Combining Both we have 750+333=1033 jackets can be manufactured and we get a YES answer to the question stem.

Hence answer

**option (C)**as we need both statements to answer the question stem.
