Sn is the only form of tin that can act as a reducing agent.

Reduction: Sn²⁺ + 2e⁻ ⟶ Sn; E° = -0.15 V

The Sn²⁺ is being reduced, so it is acting as an oxidizing agent.

Oxidation: Sn ⟶ Sn²⁺ + 2e⁻; E° = +0.15 V

The Sn is being oxidized, so it is acting as a reducing agent.

The stronger reducing agent will be $Sn^{2+}$

Explanation:

Reducing agent is defined as the agent which helps the other substance to reduce and itself gets oxidized. Thus, it will undergo oxidation reaction.

We are given:

$E_o(Sn)=0.14V\\E_o(Sn^{2+})=-0.15V$

The electrode potential values of given substances determine the tendency to gain electrons. Higher value of positive electrode potential means that it will gain more and hence, will be a stronger oxidizing agent.

If the specie has negative electrode potential, it means that it will easily loose electrons and hence, will be considered as a stronger reducing agent.

Thus, the stronger reducing agent among the given species will be $Sn^{2+}$

water molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
