Geologists have found that streams in the Karoo basin of South Africa changed suddenly at the end of the Permian period 250 million years ago,
from the meandering shape typically found in well-vegetated zones to the braided pattern found in areas without deep-rooted vegetation to hold the soil together.
(A) from the meandering shape typically found in well-vegetated zones to the braided pattern found in areas without deep-rooted vegetation to hold -- Correct(B) from the meandering shape typically found in well-vegetated zones to the braided pattern that
they find in areas without deep-rooted vegetation
for holding -- should be 'to hold'; not clear what 'it' is referring to here.(C) from the meandering shape typical in well-vegetated zones to the braided pattern found in areas where
it is without deep-rooted vegetation
for holding -- should be 'to hold'; not clear what 'it' is referring to here.(D) shifting from the meandering shape typically found in well-vegetated zones to the braided pattern found in areas where
it is without deep-rooted vegetation
for holding -- should be 'to hold'; not clear what 'it' is referring to here.(E) shifting from the meandering shape
that is typical in well-vegetated zones to the braided pattern
being found in areas without deep-rooted vegetation to hold
-- 'that is' is unnecessary' _________________
