The correct answer is option 3, which means all the given statements are correct.
Statement 1 states that the Radar Imaging Satellite (RISAT-2) is the first Indian satellite with a microwave imaging configuration on board. This means that RISAT-2 has the capability to capture images of the Earth using microwave technology, which is useful for various applications including surveillance, agriculture, and disaster management.
Statement 2 states that the satellite will boost India`s defense capabilities. This means that RISAT-2 can be used for defense purposes such as monitoring borders, identifying potential threats, and enhancing situational awareness.
Statement 3 states that RISAT-2 can take images of the Earth day and night, even under rainy and cloudy conditions. This is possible because microwave imaging technology can penetrate through clouds and atmospheric conditions, allowing for continuous imaging capabilities regardless of weather conditions.
In conclusion, all the statements are correct. RISAT-2 is the first Indian satellite with microwave imaging technology, it enhances India`s defense capabilities, and it can capture images of the Earth day and night, even under unfavorable weather conditions.
