In the case of self Biasing or potential divider biasing, for good stability factor:

1. R_B >> R_E
2. R_E >> R_B
3. R_B = R_E
4. None of these

Correct Option: B

The stability factor,

S =	β + 1(1 + R_B/R_E)	→ (A)
	1 + β + R_B/R_E

where, R_B =	R₁.R₂
	R₁ + R₂

R_E = emitter resistance
β = transistor gain
from relation we conclude that for good bias stability i.e. lower value of stability factor S, R_B << R_E.
Therefore alternative (B) is the correct choice.
