Explanation:
In this question, we need to determine which articles to use before the word "pan." Let's break down the options and analyze them one by one:

Option A:
"A/An" - This option suggests using either "a" or "an" before the word "pan." However, since "pan" does not begin with a vowel sound, we cannot use the indefinite article "an." Therefore, this option is incorrect.

Option B:
"A/The" - This option suggests using "a" before the word "pan" and "the" before the word "same." This is the correct answer because "pan" is singular and does not require the definite article "the" before it. However, "same" is a specific object, so it requires the definite article "the" before it.

Option C:
"A/A" - This option suggests using "a" before both occurrences of the word "pan." However, the second use of "pan" refers to a specific pan (the one seen in the market), so it requires the definite article "the" before it. Therefore, this option is incorrect.

Option D:
"An/The" - This option suggests using "an" before the word "pan" and "the" before the word "same." As mentioned earlier, "pan" does not begin with a vowel sound, so we cannot use the indefinite article "an." Therefore, this option is incorrect.

In conclusion:
The correct answer is option B - "A/The" because "pan" is singular and does not require the definite article "the" before it, but "same" is a specific object and requires the definite article "the" before it.
