Answer:
Atom A has SP3 Hybridization and tetrahedral geometry around the indicated carbon atoms.
Atom B has SP2 Hybridization and planar trigonal geometry around the indicated carbon atoms.
Atom C has SP2 Hybridization and linear geometry around the indicated carbon atoms.
Explanation:

Atom A : sp³ hybridized and Tetrahedral
Atom B : sp² hybridized and Trigonal planar
Atom C : sp² hybridized and Linear
Hybridization is the combination of atomic orbitals to create a new ( hybrid ) orbital which enables the pairing of electrons for the formation of chemical bonds.
The hybridization of Atom A ( in the image attached is sp³ hybridized and Tetrahedral around carbon atoms bonded to it.
The hybridization of Atom B is sp² hybridized and Trigonal planar around carbon atoms bonded to it.
Hence we can conclude that Atom A : sp³ hybridized and Tetrahedral
Atom B : sp² hybridized and Trigonal planar
Atom C : sp² hybridized and Linear .
