Lakes can form:. a. when soil becomes supersaturated
b. during hurricane activity
c. because of a collapsed volcanic caldera or subsidence caused by rifting
d. as a result of the deposition of valley walls or subsidence caused by convergence.

D

Explanation:

Idrk know how to explain this but um basically deposition of valley walls will create a river-like path which over the years creates a river I think. I just used process of elimination tbh... Hurricanes don't make rivers so B definetley isn't the correct answer. A collapsed volcanic caldera has legit nothing to do with rivers so thats a no for C. and that leaves A and D and if you poor like 100 whole jugs of water into soil its not going to create a river which leaves B as the only answer that makes sense. (I hope this somewhat helps, if need be I can try to elaborate more in the comments)

the answer is:

c. islam and christianity

explanation:

islam and christianity are widely practiced in africa. islam is practiced due to its spread from the middle east into africa, and christianity is practiced due to the colonization of africa by the british empire.
