Answer:
(d)
CA
The Evolved Laser Interferometer Space Antenna (eLISA), a mission planned that uses three separate, but not independent, interferometers installed in three spacecraft located at the corners of a triangle with sides of some 5 million km (3 million miles). This mission is to be carried out jointly by NASA and ESA.A mission to test the technology for eLISA, LISA Pathfinder, was launched by ESA in 2015. This is stationed around the L1 point between the Earth and the Sun which is nearly 1.5 million km away from the Earth. The aim of the mission is to demonstrate the technology needed to establish a space-based observatory to study gravitational waves. Therefore, the correct answer is (d).
