Answer:

The correct answer is D. 16 + 4 - 1 = 20 - 1

Step-by-step explanation:

Option A is not a true equation because 16 + 4 - 1 = 19 and not 20.

Option B is not a true equation because we're using the relational sign "less than" that is used by inequations or inequalities.

Option C is not a true equation because 16 + 4 - 1  = 19 and is not equal to 19 - 1 = 18.

Finally, option D is a true equation because 16 + 4 - 1  = 19 and is equal to 20 - 1 = 19.

The correct answer is D. 16 + 4 - 1 = 20 - 1
