Detailed Solution & Explanation

Let x\displaystyle x be the number of tables (Item A) and y\displaystyle y be the number of chairs (Item B) produced.

Let's formulate the inequalities step by step:
1) **Storage Constraint:** The total storage space can accommodate at most 100\displaystyle 100 items:
x+y100x + y \le 100
2) **Investment Constraint:** A table costs `₹ 400` and a chair costs `₹ 100`, and the total investment cannot exceed `₹ 10,000`:
400x+100y10,000400x + 100y \le 10,000
Dividing both sides of the inequality by 100\displaystyle 100 to simplify:
4x+y1004x + y \le 100
3) **Non-negativity Constraints:** The number of items produced cannot be negative:
x0,y0x \ge 0, \quad y \ge 0

Combining all constraints gives the system:
x+y100,4x+y100,x0,y0x + y \le 100, \quad 4x + y \le 100, \quad x \ge 0, \quad y \ge 0

This matches Option A perfectly.

Hence, **Option A** is the correct answer.
