1)संभाव्यता नमूना / Probability Sampling
2)सांख्यिकी विश्लेषण / Statistical Analysis
3)यादृच्छिक नमूना / Random Sampling
4)गैर-संभाव्यता नमूना / Non-probability sampling✓ Correct

Using technologically advanced manned and unmanned undersea vehicles it is possible for oceanographers to observe sea floors. Direct observations of the ocean floor are made by deep-diving submarines and some of these submarines can dive to depths of more than several miles and cruise at depths of 15 thousand feet. Radio equipped buoys can be operated by remote control in order to transmit information back to land based laboratory including data about water temperature, current and weather. Some of mankind's serious problems especially those concerning energy and food may be solved with the observations made possible with these underwater vehicles.
