Answer:
H₂O Gained Electron.
H₂O is <span>Bronsted-Lowry Base.
Explanation:
Due to amphoteric nature of water it can act as acid when reacted with strong base, also it can act as base when reacted with strong acid.
In given statement water is treated with strong acid hence it is acting as Bronsted-Lowery Base, as it accepting H</span>⁺. So those species which accepts proton are called as Bronsted-Lowry Base and those which donated proton are called as <span>Bronsted-Lowry Acid.

H₂O + H⁺ → H₃O⁺
Molecules of gas in the air absorb light of shorter wavelengths in the range of 450-495nm is an example of quantitative data.
Quantitative data is defined as the data that can be counts in number or can be measured in numbers. There are two main types of quantitative data : discreate data and the continuous data. examples are age , date, distance , weight etc. so, the countable and measurable quantities in numbers is quantitative data. Wavelength here is measured in numbers . so, wavelength is the quantitative data.
Thus, Molecules of gas in the air absorb light of shorter wavelengths in the range of 450-495nm is an example of quantitative data.

Reactions of Ethyl-3-pentenoate with all given reagents are given below.
Reaction with H₂ / Pd:
The non-polar double bond present in Ethyl-3-pentenoate is reduced to saturated chain. This reagent can not reduce the carbonyl group.
Reaction with NaBH₄: Sodium Borohydride is a weak reducing agent at compared to LiAlH₄. It can only reduce aldehydes and Ketones to corresponding alcohols.
Reaction with LiAlH₄: Lithium Aluminium hydride is a strong reducing agent. It can reduce all types of carbonyl compounds to corresponding alcohols, But, it can not reduce non-polar double bonds like alkenes and alkynes.
Result: The correct answer is
Option-A (Highlighted RED below).
