Earth revolves around the sun, keeping doldrums stationary causes the doldrums to be calm winds. Thus, the correct option is C.
<h3>
Why are the doldrums so calm?</h3>
The Intertropical Convergence Zone, also known as the doldrums or calms by sailors due to its constant lack of wind, is the area where the northeast and southeast trade winds meet. It encircles the Earth near the thermal equator, however its exact location changes with the seasons.
The sunlight beams down directly on the area around the equator, the Doldrums are caused by solar radiation from the sun. Instead of blowing horizontally, this heating causes the air to warm and climb straight up. As a result, there is little or no wind for weeks at a time.

Answer:
This is an example of scope creep. 
Explanation:
In project management, scope creep signifies the changes, uncontrolled or continuous growth in the scope of a project, at any time after the initiation of the project. This can take place when the project's scope is not adequately documented, defined, or monitored.  
The main reasons for scope creep are poor requirements analysis, underestimating the complexity of the project, not involving users early enough, and lack of change control. Thus, the given case is an illustration of scope creep.
