Recall the definition of an intensive property

An intensive property does not depend on the amount of substance or size of the system.

Examples: temperature, pressure, density.

An extensive property depends on the amount of substance.

Examples: mass, volume, heat capacity.

Check each option one by one

Option A: Molar conductivity

Molar conductivity is defined as $\Lambda_m = \frac{\kappa \times 1000}{C}$ where $\kappa$ is conductivity and $C$ is concentration.

It is a property per mole and does not depend on the total amount of solution taken, so it is treated as an intensive property.

Hence, A is correct.

Option B: Electromotive force (emf)

emf is the potential difference of a cell under open-circuit condition.

Cell potential does not depend on how much of the substance is present, as long as the concentrations remain the same. Therefore, it is an intensive property.

Hence, B is correct.

Option C: Resistance

Resistance is given by $R = \rho \frac{l}{A}$ where $\rho$ is resistivity, $l$ is length, and $A$ is cross-sectional area.

Since resistance depends on the dimensions of the conductor, it depends on system size and is therefore not intensive.

Hence, C is incorrect.

Option D: Heat capacity

Heat capacity is $C = \frac{dq}{dT}$

It depends on the amount of substance. More material means greater heat capacity.

So heat capacity is an extensive property.

Hence, D is incorrect.

The intensive properties are: $\boxed{A,\ B}$
