AI explanation

To answer this question, you need to understand the paper size standards used internationally. The paper sizes are part of the ISO 216 standard, which is widely adopted.

The ISO 216 standard defines the A series of paper sizes, with A0 being the largest and A10 being the smallest. Each subsequent size is half the area of the previous size.

Let's go through each option to understand why it is correct or incorrect:

Option A) A3 - This option is incorrect because A3 is larger than A4 and A5. A3 is twice the size of A4 and four times the size of A5.

Option B) A4 - This option is incorrect because A4 is larger than A5. A4 is twice the size of A5.

Option C) A5 - This option is correct because A5 is the smallest paper size listed. It is half the size of A4 and a quarter of the size of A3.

Option D) A2 - This option is incorrect because A2 is larger than A4 and A5. A2 is twice the size of A3 and four times the size of A4.

The correct answer is C) A5. This option is correct because A5 is the smallest paper size listed.
