c. CAD
Step-by-step explanation:
CAD provides the architect opportunity to electronically plan and place elements of a building.
CAD (Computer Aided Design) tools are used in a large variety of industries these days, including by architects.
CATIA is a CAD tool, but used to design airplanes, automobiles and ships but not buildings.
Drafting is the idea of doing a design, either on paper or on a computer, so it's not specifically electronically.
Landscape software will be used to electronically design the land layout around a building, but not the building itself.
