Abstract: It is known that every C-like space is a D -space, and every regular weakly
θ-refinable C-scattered space is also a D-space.
Is the product of these spaces also a D-space?
In this paper the above question is discussed. It is proved that the finite
product of regular weakly θ-refinable C -scattered
spaces is aD -space, and the countable product
of regular Lindel\"of C-scattered spaces is aD -space

Key words: Weakly θ -refinable, C-scattered space, D -space, ')">Lindel\"of space.
