The linear expansion coefficient is given by the formula α = Volumetric expansion coefficient / (3 × linear dimension). Here, the linear dimension is not given but we know that it is a long thin cylindrical tube. Therefore, we can assume that the linear dimension is the length of the cylinder (L), and the other dimensions (radius, diameter) are small compared to L.

Thus, we have α = 990 × 10^-6 / (3 × L).

Substituting the value of L = 1 (considering it as 1 meter for simplicity), we get α = 330 × 10^-6 / K. Hence, the correct answer is option (B).
