Hint: A triple bond is a chemical bond in which two atoms are involved by six bonding electrons instead of the usual two bonding electrons that are present in cases of a single covalent bond. Alkynes is one example in which triple bond is found.

Complete step by step answer:
As we know that the sigma bond is a covalent type of bond (in which electrons are shared) which is formed by head-on overlapping of atomic orbitals. The sigma bonds are represented by symbols ($\sigma $). The sigma bonds are the strongest covalent bonds. Generally, all the single bonds are sigma bonds. The sigma bonds can be formed by overlapping the following orbitals: $s - s,s - p,p - p$.
On the other hand, the pi bond is also a covalent type of bond which is formed by the sidewise overlapping or parallel overlapping of the atomic orbitals. The pi bonds are represented by the symbol $(\pi )$. In sigma bonds, the axis of the atomic orbitals are parallel to each other. The pi bonds are weaker bonds than the sigma bonds.
In case of a single bond, it contains only one sigma bond, in case of double bond it contains one sigma and one pi bond and in case of triple bond it contains one sigma and two pi bonds.

Hence, option C.) is the correct answer.

Note:
Always remember that if a chemical compound contains a single bond then it is sigma bond, if compound contains a double bond then it contains one sigma and one pi bond and if compound contains triple bond then it contains one sigma bond and two pi bonds. We can remember that every bond (whether it is single, double or triple bond )contains one sigma bond.
