Solution
The correct option is C Assertion is correct but Reason is incorrect
Primary succession is the biotic succession that occurs on a
previously sterile or primary bare area. Newly exposed sea floor,
igneous rocks, sand dunes, new cooled lava sediments or newly submerged
area are some of the examples of primary bare area. Soil and humus is
absent at the beginning of primary succession and reproduction
structures of any previous community are absent. Thus, the environment
is very hostile for pioneer community and primary succession takes a
long time for completion.So, the correct answer is 'Assertion is correct but Reason is incorrect'.
