Assertion (A): Derivative control action cannot be used alone.

Reason (R): Derivative control action is effective only during transient periods.

Assertion (A): In circular waveguide the attenuation of TE₀₁ mode decreases as the operating frequency increases.

Reason (R): The wall currents in a circular waveguide in TE_Q1 mode are completely circumferential.

Assertion (A): Microprocesspr 8085 has six 8 bit registers B, C, D, E, H L.

Reason (R): B - C, D - E, H - L may be combined to form register pairs to hold 16 bits data.
