Answer 1

Correct answer is (b) Greaseproof paper

The best explanation: Greaseproof paper is often used for packaging butter and similar fatty foods. The satisfactory performance of greaseproof papers depends on the extent to which the pores have been closed. Provided that there are few interconnecting pores between the fibers, the passage of liquids is difficult. However, they are not strictly “greaseproof” because oils and fats will penetrate them after a certain interval of time. Despite this, they are often used for packaging butter and similar fatty foods since they resist the penetration of fat for a reasonable period.
