Match the following properties with their respective units.

Property		Unit
P.	Notched Izod impact strength	1.	Pa s
Q.	Flexural strength	2.	J m^-1
R.	Dielectric strength	3.	MPa
S.	Complex viscosity	4.	kV cm^-1

Answer: C

The correct matching is P-2; Q-3; R-4; S-1.

Notched Izod impact strength is the energy absorbed per unit notch width, in J m^-1 (P-2).
Flexural strength is a stress, in MPa (Q-3).
Dielectric strength is the breakdown voltage per unit thickness, in kV cm^-1 (R-4).
Complex viscosity, from oscillatory rheometry, is a viscosity, in Pa s (S-1).

The other options give impact strength the unit of viscosity or stress, or swap the units of flexural and dielectric strength.
