Function strcpy() is used to copy the contents of one string into another including the null character. In this case, it will copy "goodbye" into "good morning" replacing "morning" with "goodbye". Option A correctly uses the strcpy function to perform this operation. Option B is incorrect because the function strcpy() only takes two parameters, and not three. Option C copies only the first 5 characters of string2 into string1, but does not include the null character, which can cause unexpected behavior. Option D is similar to C, but copies 6 characters, including the null character, which also results in unexpected behavior.
