Answer:
A. TRUE
Step-by-step explanation:
The XOR formula is a logical operator that returns TRUE if one of the expressions is true and the other is false, and it returns false if both expressions are true or false.
In this case the formula =XOR(120<102;83=83;51<24) calculates
120<102 =FALSE;
83=83 = TRUE;
51<24 = FALSE;
As only one of the expressions is true and the other two are false, the XOR formula returns TRUE.
