B.2 and 4
D.2 and 3

Correct Answer: Option A

The question is about Polyethylene terephthalate (PET or PETE).

Here's an analysis of each statement:

Statement 1 (Correct): PET fibers are frequently blended with other fibers like rayon, wool, and cotton to enhance their inherent qualities. Statement 1 is correct.

Statement 2 (Incorrect): Using plastic packaging for alcoholic beverages poses risks to human health, making it unsuitable for storing any alcoholic beverage. Statement 2 is not correct.

Statement 3 (Correct): PET bottles stand out as they can be recycled into the same form repeatedly, allowing them to be transformed into new beverage bottles. Statement 3 is correct.

Statement 4 (Incorrect): The production and incineration of plastic contribute significantly to greenhouse gas emissions, releasing substantial amounts into the atmosphere. Statement 4 is not correct.

Hence, only statements 1 and 3 are correct.
