E. I, II, and III


6\(\triangle\)3\(\leq{3}\)

\(\frac{6}{3} = 3\)

\(6 - 3 = 3\)


\(\triangle\) has to be division and subtraction both.

Checking the options, we get;

I. 2\(\triangle\)2=0

\(2 - 2 = 0.\)

\(\frac{2}{2}\) = 1 ---------- (Must Not be true)

II. 2\(\triangle\)2=1

\(\frac{2}{2}\) = 1.

\(2-2 = 0\) ---------- (Must Not be true)

III. 4\(\triangle\)2=2

\(4-2 = 2.\)

\(\frac{4}{2}\) = 2 -----------(Must be true)

Only III must be true. Answer (C).

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 = 9
2. 6 - 3 = 3
3. 6 * 3 = 18
4. 6 / 3 = 2

Of 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.
