A.0.2-0.5 cm/yr
B.2-10 cm/yr
C.50-100 cm/yr
D.10-20 m/yr

Answer 1

b . 2-10 cm/yr ))))))))))

Answer 2

Option B, 2-10 cm/yr

Step-by-step explanation:

Normally the tectonic plates move at a rate of
`0.60`cm/yr to
`10`cm/yr.

How ever most of the tectonic plates move at an average rate of
`2-3`cm/yr.

The tectonic plates in the pacific ocean known as" Cocos and Nazca plates" are the fastest moving tectonic plate. Their rate of displacement is
`10`cm/yr

Hence, option B is correct.
