Please I just want to understand. Can you give me more detail

Thank you.
Suppose X₁, X₂, X3 denotes a random sample from the exponential distribution with density function x>0 f(x) elsewhere Consider the following four estimators of 0: X₁ + X₂ 6₁ = X₁ 2 X₁ + 2X₂ Ô4 = X ês= 3 a Which of the above estimators are unbiased for 0? b Among the unbiased estimators of 0, which has the smallest variance? 2X₁ + X₂ + X3 3
