    Consider the following statements with reference to the Gravitational...

    Explanation:

    1. They can penetrate regions of space that electromagnetic waves cannot.
    Gravitational waves are not obstructed by matter, which allows them to travel through regions of space that electromagnetic waves cannot penetrate. This unique property makes them valuable for observing events such as the merger of black holes and other exotic objects in the distant Universe.

    2. They allow the observation of the merger of black holes and other exotic objects in the distant Universe.
    Gravitational waves provide a new way of observing the Universe, allowing scientists to detect events such as the merger of black holes and neutron stars. These observations provide valuable insights into the nature of these exotic objects and their interactions.

    3. Its precise measurements will allow scientists to test more thoroughly the general theory of relativity.
    By studying the properties of gravitational waves and their behavior, scientists can test the predictions of the general theory of relativity with unprecedented accuracy. This allows for a more thorough validation of Einstein's theory and opens up new possibilities for understanding the fundamental nature of gravity.

    Therefore, all three statements are correct in relation to gravitational waves and their significance in the field of astrophysics.

    Consider the following statements with reference to the Gravitational...
    • Gravitational waves can penetrate regions of space that electromagnetic waves cannot. So, statement (1) is correct.
    • Gravitational waves allow the observation of the merger of black holes and other exotic objects in the distant Universe. So, statement (2) is correct.
    • Such systems cannot be observed with more traditional means such as optical telescopes or radio telescopes, and so gravitational wave astronomy gives new insights into the working of the Universe.
    • In particular, gravitational waves could be of interest to cosmologists as they offer a possible way of observing the very early Universe. This is not possible with conventional astronomy, since before recombination, the Universe was opaque to electromagnetic radiation. Precise measurements of gravitational waves will also allow scientists to test more thoroughly the general theory of relativity. So, statement (3) is correct.
    Therefore, the correct answer is (d).
