The two sources of energy in remote sensing are:

1. Active Remote Sensing: In active remote sensing, energy is generated and sent from the remote sensing instrument towards the target to be investigated. The energy reflected back from the target is then detected and measured by the sensor. Examples of active remote sensing include radar and LIDAR.

2. Passive Remote Sensing: In passive remote sensing, the natural energy that is reflected or emitted from the observed scene is detected and measured by the sensor. This could be sunlight reflected from the earth's surface or heat energy emitted from the surface. Examples of passive remote sensing include photography, infrared, charge-coupled devices (CCD), and radiometers.

So, the correct answer is B. Active and passive.
