The correct answer are:    "44 – 24" , "12 + 8" and "30 – 10".

Solution:

To identify the correct option, we check all the given options.

44 – 24 = 20

12 + 8 = 20

30 – 10 = 20

We observe that, out of all the options, 44 – 24,  12 + 8  and  30 – 10 are the options that make the number 20.

So, 44 – 24,  12 + 8  and  30 – 10 are the correct options.
