Which of the following combinations should be selected for better tuning of an LCR circuit used for communication?
A. R = 20 Ω, L = 1.5 H, C = 35μF.
B. R = 25 Ω, L = 2.5 H, C = 45μF.
C. R = 15 Ω, L = 3.5 H, C = 30μF.
D. R = 25 Ω, L = 1.5 H, C = 45μF.

The quality factor

Q=\frac{1}{R}\sqrt{\frac{L}{C}}

where R is resistance, L is the inductance and C is the capacitance of the circuit

For a higher Q, L must be larger, and R and C must be smaller in value.
