To determine which of the following compounds contains a metalloid, we first need to understand what a metalloid is. Metalloids are elements that have properties of both metals and nonmetals and typically include Boron (B), Silicon (Si), Germanium (Ge), Arsenic (As), Antimony (Sb), and Tellurium (Te).

Given the compounds:

A. [tex]\( SiF_4 \)[/tex]

- This compound contains Silicon (Si), which is a metalloid.

B. [tex]\( SCl_2 \)[/tex]

- This compound consists of Sulfur (S) and Chlorine (Cl). Neither of these elements are metalloids.

C. [tex]\( In_2O_3 \)[/tex]

- This compound consists of Indium (In) and Oxygen (O). Neither of these elements are metalloids.

D. [tex]\( Sn(C_2H_5)_4 \)[/tex]

- This compound consists of Tin (Sn) and an ethyl group (C₂H₅). Tin is a metal and ethyl groups are made of carbon and hydrogen, neither of which are metalloids.

E. [tex]\( Bi_2S_3 \)[/tex]

- This compound consists of Bismuth (Bi) and Sulfur (S). Bismuth is a metal and Sulfur is a nonmetal; neither are metalloids.

Since Silicon (Si) is a metalloid and only compound A ([tex]\( SiF_4 \)[/tex]) contains Silicon, the compound that contains a metalloid is:

[tex]\[ \boxed{A} \][/tex]
