To determine the correct chemical formulae of the main compounds in haematite and limestone, let's break down the information we know:

1. Identify the Compound in Haematite:
- Haematite (also spelled hematite) is primarily composed of iron(III) oxide. The common formula for iron(III) oxide is [tex]\( Fe_2O_3 \)[/tex].

2. Identify the Compound in Limestone:
- Limestone is primarily composed of calcium carbonate. The chemical formula for calcium carbonate is [tex]\( CaCO_3 \)[/tex].

Now let's match these formulae with the given options:

- Option A:
- Haematite: [tex]\( Fe_2O_3 \)[/tex]
- Limestone: [tex]\( CaCO_3 \)[/tex]

- Option B:
- Haematite: [tex]\( Fe_2O_3 \)[/tex]
- Limestone: [tex]\( Ca(CO)_3 \)[/tex]

- Option C:
- Haematite: [tex]\( Fe_3O_2 \)[/tex]
- Limestone: [tex]\( CaCO_3 \)[/tex]

- Option D:
- Haematite: [tex]\( Fe_3O_2 \)[/tex]
- Limestone: [tex]\( Ca(CO)_3 \)[/tex]

From this, we can see:

- [tex]\( Fe_2O_3 \)[/tex] is the correct chemical formula for haematite.
- [tex]\( CaCO_3 \)[/tex] is the correct chemical formula for limestone.

Therefore, the correct matching option from the given choices is:

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

Thus, the correct chemical formulae of the main compounds in haematite and in limestone are [tex]\( Fe_2O_3 \)[/tex] and [tex]\( CaCO_3 \)[/tex], respectively, which corresponds to Option A in the given table.
