How would I make an instantiated object appear at exact level of my terrain

Question

How can I make sure instantiated objects are always going to be placed at the height of my terrain

Although my game is 3D the placement of objects/prefabs takes place in a top down view almost exactly the way its done in RTS games. (The object will be placed according to where the mouse is clicked)

Two methods come to mind

Raycast down from a suitable height above the terrain
Read the height from a height map

For most applications the raycasting will do fine. If you are after supreme commander like numbers of units, then explicitly reading from a height map will perform better.
