Answer:

Newton per square meter (N/m2)

Explanation:

Required

Unit of ultimate tensile strength

Ultimate tensile strength (U) is calculated using:

[tex]U = \frac{Ultimate\ Force}{Area}[/tex]

The units of force is N (Newton) and the unit of Area is m^2

So, we have:

[tex]U = \frac{N}{m^2}[/tex]

or

[tex]U = N/m^2[/tex]

Hence: (c) is correct
