The correct answer is B. 255.
A text field is a field in a database that can store text. The maximum length of a text field is 255 characters. This means that you can store up to 255 characters in a text field.
Option A is incorrect because the maximum length of a text field is 255 characters, not 120 characters.
Option C is incorrect because the maximum length of a text field is 255 characters, not 265 characters.
Option D is incorrect because the maximum length of a text field is 255 characters, not 75 characters.
