If the sum of the distances of a point from two perpendicular lines in a plane is 1, then its locus is
(a)a square  (b)  a circle (c) a straight line         (d)  two intersecting lines

Options

A. a square
B. a circle
C. a straight line
D. two intersecting lines

Explanation

To solve the problem, we need to find the locus of a point (h, k) such that the sum of its distances from two perpendicular lines in a plane is equal to 1.

### Step-by-Step Solution:

1. **Assume the Point**:
Let the point be \( P(h, k) \).

2. **Equations of the Lines**:
