Correct option is D
Microwave remote sensing is widely used for observing Earth's surface and atmosphere due to its ability to penetrate clouds and operate day or night. It effectively monitors:
• Soil moisture (A)
• Canopy cover (B)
• Snow cover (C)
• Atmospheric moisture profiling (D)
• Ocean parameters like circulation and winds (E)
Hence, all options listed are correct applications of microwave remote sensing.
