- ABoth variables are pure numbers.
- BBoth variables are in the same unit.
- CBoth variables are in different units.
- DAt least one variable is a pure number.
Explanation
Along a 45-degree line through the origin, the geometric equality of the axes only implies the algebraic equality X = Y if both variables are measured in the same unit. With different units the 45-degree line would be meaningless. Hence B.
