Correct Answer : c
Explanation :  l2 + m2 + n2 = 1
(a) 9 + 16 + 25 not equal to 1
(b) y = 4z
4 is not equal to 20
(d) x + y - z = 0
3 + 4 - 5 = 0
=> 2 is not equal to 0
There option c satisfies the equation.

Explanation:

Direction Numbers of a Line in Space:
- In three-dimensional space, a line can be defined by its direction numbers.
- Direction numbers are the ratios of the direction cosines of the line.
- The direction numbers of a line are usually represented by three integers (a, b, c).
- For example, the direction numbers of a line passing through points (3, 4, 5) and (-1, 0, 1) are (4, -4, -2).

Therefore, the numbers 3, 4, 5 can be interpreted as direction numbers of a line in space.
