To determine the correct formula for silicon tetrachloride, we need to understand the components and their chemical bonding.

1. Identify the elements involved:
- Silicon (Si)
- Chlorine (Cl)

2. Determine the valency of the elements:
- Silicon is in group 14 of the periodic table and has a valency of 4.
- Chlorine is in group 17 of the periodic table and has a valency of 1.

3. Combine the elements in such a way that the total valencies balance each other out:
- Silicon, with a valency of 4, can form bonds with four chlorine atoms, each having a valency of 1.

Based on the valency, the correct formula for silicon tetrachloride is one silicon atom bonded with four chlorine atoms.

Thus, the correct option is:
B. [tex]\( SiCl_4 \)[/tex]

So, the formula for silicon tetrachloride is [tex]\( SiCl_4 \)[/tex].
