Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Remote sensing is the science of obtaining information about objects without physical contact.
Common remote sensing methods include:
• Thermal sensing.
• Multispectral scanning.
• Microwave sensing. An Earth resource satellite is not a sensing method; it is a platform that carries remote sensing sensors.
Step 1: Identify the sensing methods. Thermal, multispectral and microwave sensing are all techniques used to acquire remote sensing data.
Step 2: Identify the non-method. An Earth resource satellite serves as the carrier of sensors rather than being a sensing method. Hence, \[ \boxed{\text{Earth resource satellite is not strictly a remote sensing method}.} \] Therefore, the correct option is \[ \boxed{(C)\;\text{Earth resource satellite}.} \]
