Since the symbol \(\triangle\) is one of the four primary arithmetic operations - addition, subtraction, multiplication, or division

6\(\triangle\)

3 could mean one of the four things

1.

6 + 3 = 92.

6 - 3 = 33.

6 * 3 = 184.

6 / 3 = 2Of these options only 2. subtraction and 4. division can be the arithmetic operation as they satisfy the condition

6\(\triangle\)

3\(\leq{3}\)

Of the three options, we need to examine

I. 2\(\triangle\)2=0 is true for subtraction but not for division

II. 2\(\triangle\)2=1 is true for division but not for subtraction

III. 4\(\triangle\)2=2 is possible for both subtraction and division.

Therefore,

Option C(III only) is the only option which must be true for both the arithmetic operations.
