Continental drift speed is 1x10^-9 meter per second. this is equivalent to the speed of 1.) 1 tm/s 2.) 1 gm/s 3.) 1 nvm/s 4.) 1 pm/s

Explanation:

The continental drift speed is,

The options have some prefix. These are as follows :

1. Tera (T) =                

2. Giga (G) =    

3. Nano (n) =      

4. Pico (p) =

The speed of continental drift is equivalent to 1 nm/s. So, the correct option is (c).
