**Solution:**

Option(**B**) is correct

Let the total number of couriers be $360N$ while the Total Cost be $360C$ for ABC Ltd. in the year 2006.

So the cost per courier for:

Road transport,

$=\dfrac{72C}{150N}$

$=\dfrac{ 0.48C}{N}$

Rail transport,

$=\dfrac{90C}{120N}$

$= \dfrac{ 0.75C}{N}$

Air transport,

$=\dfrac{198C}{90N}$

$=\dfrac{ 2.2C}{N}$

It is clear from the above that the **Road** transport has the least cost of transport per courier.
