best_answer

As we learnt,

Lithium and its alloys -

Lithium +Lead = white metal bearings for motor engines

Lithium + aluminium = aircraft parts

Lithium + magnesium = armour plates

Lithium = electrochemical cells

White metal is an alloy of Lead and Lithium metal, and these white metal bearings are used in motor engines.

Also, Pb + Li with aluminium is used to make aircraft parts.

Pb + Li with magnesium makes armour plates, thermonuclear reactions, and electrochemical cells.

Therefore, option (2) is correct.
