Which of the following terms is related to linear programming problems?

A. Fisher's Method
B. Constraints
C. Optimal product line-problems
D. The least square methods of trends
E. Baye's theorem

Choose the correct answer from the options given below:

B & C only

The correct answer is Option (2) → B & C only

$\text{Linear Programming involves constraints and optimization problems}$

$\text{B: Constraints} \;\Rightarrow\; \text{Yes}$

$\text{C: Optimal product line problems} \;\Rightarrow\; \text{Yes}$

$\text{A: Fisher's Method} \;\Rightarrow\; \text{Index numbers (Not LPP)}$

$\text{D: Least square method} \;\Rightarrow\; \text{Trend analysis (Not LPP)}$

$\text{E: Baye's theorem} \;\Rightarrow\; \text{Probability (Not LPP)}$

The correct options are B and C.
