Step 1: Understanding the Concept:
The question asks to identify the specific welfare provision covered under Section 49 of the Factories Act, 1947. The Act mandates several welfare measures for workers, and specific sections are dedicated to each of them.
Step 2: Detailed Explanation:
Let's analyze the relevant sections of the Factories Act, 1947, related to worker welfare:
\[\begin{array}{rl} \bullet & \text{Section 46: Deals with the provision of Canteens in factories where more than two hundred and fifty workers are ordinarily employed. } \\ \bullet & \text{Section 47: Deals with the provision of shelters, Rest rooms, and lunch rooms in factories where more than one hundred and fifty workers are ordinarily employed. } \\ \bullet & \text{Section 48: Deals with the provision of Crèches in factories where more than thirty women workers are ordinarily employed. } \\ \bullet & \text{Section 49: This section explicitly mandates the appointment of Welfare Officers. It states that in every factory where five hundred or more workers are ordinarily employed, the occupier shall employ in the factory such number of welfare officers as may be prescribed. } \\ \end{array}\]
Based on this, Section 49 is the provision that deals with the appointment of a Welfare Officer.
Step 3: Final Answer:
The correct answer is (C) because Section 49 of the Factories Act, 1947, specifically contains the provision for the appointment of Welfare Officers.
