Which of the following eons has no rock record?

phanerozoic
proterozoic
archean
hadean

Option (4)

Explanation:

Hadean Eon refers to the initial period of formation of earth ranging from about 4.6 billion to 4.0 billion years ago. During this eon, the dust particles and gases were accumulated and collision of planetesimals took place. Heavy bombardment has taken place at that time and eventually led to the formation of the dense core to the rigid outer crust. With the increase in time, the atmosphere and oceans started to develop.

Thus, the Hadean eon has no record of any rock sequence.
