Solution

The correct option is C $T_{A} > T_{C} > T_{B}$
According to Wien's Displacement law we know that:-
$λ = \frac{b}{T} \dots \dots (1)$ .

Given that three stars $A, B$ and $C$ where $A$ appears bluish, $B$ appears reddish and $C$ appears yellowish.

We know that $λ_{b l u e} < λ_{y e l l o w} < λ_{R e d}$
$⟹ λ_{A} < λ_{C} < λ_{B} . . . . . (2)$

from (1) and (2) we get
$⟹ T_{A} > T_{C} > T_{B}$

Hence option $(A)$ is correct
