Let P_ij = the production of product i in period j.To specify that production of product 1 in period 3 and in period 4 differs by no more than 100 units,we would write it as A)P₁₃ − P₁₄ ≤ 100; P₁₄ − P₁₃ ≤ 100. B)P₁₃ − P₁₄ ≤ 100; P₁₃ − P₁₄ ≥ 100. C)P₁₃ − P₁₄ ≤ 100; P₁₄ − P₁₃ ≥ 100. D)P₁₃ − P₁₄ ≥ 100; P₁₄ − P₁₃ ≥ 100.

To specify that production of product 1 in period 3 and period 4 differs by no more than 100 units, we need to write two inequalities, one for each possible direction of the difference. The first inequality would be P₁₃ - P₁₄ ≤ 100, indicating that the production in period 3 cannot be more than 100 units greater than the production in period 4. The second inequality would be P₁₄ - P₁₃ ≤ 100, indicating that the production in period 4 cannot be more than 100 units greater than the production in period 3. Therefore, the correct choice is A, which includes both of these inequalities.
