Which of the following house hold plastic material is used to prepare drinking straws ?

Step-by-step solution

PVC is a rigid plastic used primarily for construction materials and insulation, not typically for drinking straws due to its inflexibility. LDPE lacks sufficient structural rigidity for straw applications despite its flexibility. PS is brittle and not ideal for the bending required in typical straw usage. PP possesses the optimal combination of flexibility, chemical resistance, and durability required for drinking straws, making it the standard material choice. The correct identification is D .
