D.10-20 m/yr

Answer 1

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

Answer 2

Answer:

Option B, 2-10 cm/yr

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.
