(b) 760 mm Hg

#### Explanation:

Look at the units...

(a) Pa - Pa is the SI unit of Pascals, a unit of **Pressure**

(b) mm Hg - Hg is the elemental symbol for **Mercury**

(c) atm - Atm stands for Atmosphere and is a unit of **Pressure**

(d) kPa- stands for kilo *Pascal* and is also a unit of **Pressure**

(b)Mercury is the only element and not a unit of pressure, therefore it is not equivalent to the remaining three
