{'low frequency array': [0, 0, 0, 1], 'powerful radio antenna': [0, 0, 0, 1], 'lofar': [0, 0, 0, 1], 'wireless communication technology': [0, 0, 0, 2], 'space technology': [0, 1, 0, 0], 'satellites': [0, 1, 0, 0], 'satellite navigation system': [0, 0, 0, 1], 'nasa': [0, 0, 0, 1], 'space': [4, 1, 7, 12]}

Option 1 is the correct answer. LOFAR (Low Frequency Array) is not the world`s most powerful radio antenna. LOFAR is a radio telescope network that operates in the low frequency range. It consists of thousands of dipole antennas spread throughout Europe, forming a dense array. The data collected by LOFAR is processed and combined to create high-resolution images of the Universe.

Option 2 is incorrect. LOFAR is not a space technology launched by NASA to discover exoplanets. The purpose of LOFAR is not to discover exoplanets but to study various astrophysical phenomena such as pulsars, cosmic rays, and the formation of galaxies.

Option 3 is incorrect. LOFAR is not an arrangement of satellites in space for the purpose of creating a Satellite Navigation System. LOFAR is a ground-based radio telescope network.

Option 4 is incorrect. LOFAR is not a wireless communication technology for 5G services. It is a scientific instrument used for astronomy research, not for providing wireless communication services.
