Answer
A reducing agent is a substance that donates electrons in a chemical reaction. The strength of a reducing agent is generally determined by its ability to lose electrons easily.

Answer
Fluorine (F): Fluorine is a powerful oxidizing agent rather than a reducing agent because it tends to gain electrons.
Lithium (Li): Lithium can easily lose an electron, making it a good reducing agent.
Calcium (Ca): Calcium is also a strong reducing agent, having a tendency to donate electrons.
Iodine (I): Iodine is less likely to donate electrons compared to lithium and calcium.

Answer
Among the options, Lithium (B) is the strongest reducing agent due to its high electronegativity and low ionization energy, allowing it to readily lose its outer electron.
