The correct answer is: A. Fossil : Aged
Zephyr is a gentle breeze, while a gale is a strong wind. A fossil is the remains or impression of a prehistoric plant or animal embedded in rock. An aged person is old.
B. Imprint : Emboss
An imprint is a mark or impression left by something, while embossing is the process of making a raised design on paper or other material.
C. Trickle : Torrent
A trickle is a small stream of water, while a torrent is a violent flood of water.
D. Death : Sickness
Death is the end of life, while sickness is an illness.
In each of the other options, the two words do not have the same relationship as the original pair of words. For example, in option B, an imprint is not necessarily a result of embossing.
