\(\text {Trigonal\ bipyramidal}\)
In the trigonal bipyramidal geometry, the central iron atom is surrounded by five ligands (carbon monoxide molecules). Three of these \(\text {CO}\) ligands are arranged in a trigonal plane, while the other two are located above and below the plane, making the shape trigonal bipyramidal.
So, the correct option is (C): Trigonal bipyramidal

Such a group of atoms is called a molecule. Obviously, there must be some force that holds these constituent atoms together in the molecules. The attractive force which holds various constituents (atoms, ions, etc.) together in different chemical species is called a chemical bond.
There are 4 types of chemical bonds which are formed by atoms or molecules to yield compounds.
