Answer:
C. transition elements
Explanation:
Transition elements are groups of metallic elements that have partially filled d orbitals. They occupy the d-block of the periodic table (Group 3-12). Examples of elements that fall under this category are Nickel (Ni), Cobalt (Co), Copper (Cu), Zinc (Zn) etc. Transition metals have outstanding properties that distinguishes them from other elements.
One of these properties is their ability to form colored compounds due to their unfilled d electron shells. They form ions that are usually colored in solid compounds and in solution.

atoms of titanium are present in a sample containing 0.375 moles of Ti.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 × 10^{23} of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
To find the number atoms we need to multiply by 6.02214076 × 10^{23}.
0.375 moles x 6.02214076 × 
2.258302785 x 
Hence, 2.258302785 x
atoms of titanium are present in a sample containing 0.375 moles of Ti.
