For the supply of materials for concrete, form work reinforcing and placing of concrete, removal of form work and curing of concrete, number of bar(s) required on bar chart, is

A 1
B 2
C 3
D 4

Correct Answer: 4

This is the correct answer. In construction project management using a bar chart (Gantt chart), each activity is represented by a horizontal bar. The activities mentioned in the question include:

1. Supply of materials for concrete
2. Formwork, reinforcing, and placing of concrete
3. Removal of formwork
4. Curing of concrete
Each of these activities requires a separate bar on the chart.
