The correct answer are:    "18 + 7" , "29 – 4" and "16 + 9".

Solution:

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

18 + 7 = 25

29 – 4 = 25

16 + 9 = 25

32 – 12 = 20

We observe that, out of all the options, 18 + 7,  29 – 4 and  16 + 9 are the options that make the number 25.

So, 18 + 7,  29 – 4 and  16 + 9 are the correct options.
