Hint: The methane \[C{H_4}\] molecule is the best example of\[s{p^3}\]hybridization. In which one \[s\]and three\[p\]orbital are involved in hybridization and form four \[s{p^3}\]hybridized orbital of the same energy. These four orbitals have a tetrahedral arrangement around the carbon center. Other examples of \[s{p^3}\]hybridization involve \[{C_2}{H_6}\]and \[Si{(C{H_3})_4}\], etc.
Complete step by step solution:The process of hybridization involves the mixing of atomic orbitals of an atom to produce new atomic orbitals of different shapes, sizes, and energy. These new orbitals are called hybrid orbitals.
In hybridization, the half-and fully filled orbital can take part.
By employing the concept of hybridization, we can easily predict the geometry of the molecules.
Based on the mixing of orbitals, the hybridization can be classified in the following way:
(1) \[s{p^{}}\]hybridization: Involve mixing of one \[s\]and one\[p\]orbitals. It has 50% \[s\]and 50%\[p\]characters with linear geometry. E.g., the acetylene molecule.
(2) \[s{p^2}\]hybridization: Involve mixing of one \[s\]and two\[p\]orbitals. It has 33.33% \[s\]and 66.66%\[p\]character with trigonal planar geometry. E.g., \[B{H_3}\] molecule.
(3) \[s{p^3}\]hybridization: Involve mixing of one \[s\]and three\[p\]orbitals. It has 25% \[s\]and 75%\[p\]character with tetrahedral geometry. E.g., \[C{H_4}\] molecule.
(4) \[s{p^3}d\]hybridization: Involves mixing of one \[s\], three\[p\]and one \[d\] orbitals. It has trigonal bipyramidal geometry. E.g., \[PC{l_5}\] molecule.
(5) \[s{p^3}{d^2}\]hybridization: Involves mixing of one \[s\], three\[p\]and one \[d\] orbitals. It has octahedral geometry. E.g., sulfur hexafluoride.
The tetramethyl silane (\[Si{(C{H_3})_4}\]) or TMS has a very similar structure to the methane (\[C{H_4}\]) molecule. In \[Si{(C{H_3})_4}\] molecule one \[s\]and three\[p\]orbital involved in hybridization and produce four \[s{p^3}\]hybridized orbitals. These four orbitals have a tetrahedral arrangement around the silicon (\[Si\])center and form four sigma bonds with four\[C{H_3}\] groups.

Therefore from the above explanation we can say option (d) will be the correct option:
Note: tetramethyl silane is a volatile organometallic compound.
In NMR spectroscopy tetramethyl silane is used as an internal standard to calibrate the chemical shift.
tetramethyl silane is responsible for memory loss and brain tumors in human beings.
In organic chemistry tetramethyl silane acts as a protecting group for alcohols.
