Right.

(2.) Change february to February

To determine the correct correction for the sentence, let's analyze each option:

1) Change "friends" to "friend's": This correction is not necessary since "friends" is referring to multiple individuals and does not require possession.

2) Change "february" to "Februauy": This correction addresses a typo in the word "February." If this typo is present in the sentence, this correction would be appropriate.

3) Remove the comma after "years": This correction suggests that the comma after "years" should be removed. If the sentence does not require a pause or separation between the listed items, removing the comma would be the suitable correction.

4) Change "summer" to "Summer": This correction suggests that the word "summer" should be capitalized. If the word "summer" is used as a proper noun (referring to a specific event or place), it should be capitalized. However, if it is used in a general sense, it does not require capitalization.

5) Change "haven't" to "have'nt": This correction suggests that the word "haven't" should be changed to "have'nt." However, this correction is incorrect, as the correct spelling of the contraction "haven't" is "haven't" without an apostrophe.

Considering all the options, the most appropriate correction for the given sentence would be:

2) Change "february" to "February" (if the typo is present) and/or
3) Remove the comma after "years" (if a pause or separation is not necessary).
