Explanation:

1 and 3 only

The given pairs regarding Mineral Groups occurring in different layers of the Earth are as follows:

Crust - SiMa (Silica + Magnesium)

Mantle - SiAl (Silica + Aluminum)

Core - NiFe (Nickel + Iron)

Among the pairs:

The pair "Crust - SiMa" (Silica + Magnesium) is a generally accurate representation. The Earth's crust consists mainly of silicate minerals, including silica and magnesium-rich minerals.

The pair "Mantle - SiAl" (Silica + Aluminum) is not an accurate representation. The Earth's mantle primarily consists of silicate minerals but is not predominantly aluminum-rich. It contains various minerals and compounds, but aluminum is not a defining characteristic.

The pair "Core - NiFe" (Nickel + Iron) is a correct representation. The Earth's core is composed mainly of nickel and iron, making it NiFe.

Therefore, only the pairs 1 and 3 are correctly matched
