The correct option is D.
Transition metals are those metallic elements that are located in the central block of the periodic table. They exhibit various valency states and they generally have various colors. The atomic radius of an element refers to the measure of the size of its atom. For transition metals, their atomic radii decrease slightly and then start to increase, when one is moving from the left to the right of the periodic table.
Answer : The correct option is, Atomic radii decrease slightly and then start to increase.
Explanation :
Transition metals : It is defined as the element whose atom is ground state or ion in one of the common oxidation states, has incomplete d-subshell.
The general trend of atomic radii of transition metals is :
Generally the atomic radii of d-block elements in a series decreases with increase in atomic number but decreases in atomic size is small after midway that means almost remains same and at the end of the period there is a slight increase in the atomic radii.
Hence, the atomic radii decrease slightly and then start to increase of the transition metals when moving from left to right on the periodic table.

The electron is the primary atomic particle that determines an atom's chemical behaviour.
Electrons are negatively charged particles that form electron shells or energy levels around an atom's nucleus. They are engaged in the production and breaking of chemical bonds, hence they play an important part in chemical reactions.
The quantity and configuration of electrons in an atom's outermost energy level (valence electrons) are very significant in determining the chemical characteristics of the atom. Because of the identical number of valence electrons, elements in the same group or column of the periodic table frequently show similar chemical behaviour.
