Answer:
Rank of acid-base definitions from most specific to most general is-
Arrhenius, Bronsted-Lowry, Lewis
Explanation:
Arrhenius acids are those which contain H atom and furnish proton () in aqueous solution. Arrhenius bases are those which contain -OH group and furnish
in aqueous solution.
Bronsted-Lowry acids are those which can donate protons. Bronsted-Lowry bases are those which can accept proton.
So clearly, Bronsted-Lowry acids are also Arrhenius acids and Bronsted-Lowry bases are also Arrhenius bases .
Lewis acids are those which can accept electrons. Lewis bases are are those which can donate electrons.
So, donating or furnishing of proton alternatively suggests acceptance of electrons. Also consumption of proton alternatively suggests donation of electrons.
Hence Lewis acid-base are also Arrhenius acid-base as well as Bronsted-Lowry acid-base.

Answer: The correct option is 2.
Explanation: There are two types of nuclear reactions:
1) Nuclear fission: These reactions are defined as the reactions in which a heavier unstable nuclei breaks into two or more smaller stable nuclei.
2) Nuclear fusion: These reactions are the ones where two smaller nuclei fuse together or combine together to form a larger nuclei.
In the question, we need to find the fusion reaction which forms elements heavier than helium.
Option 1: In this fusion reaction occurs but the nuclei is Helium itself.
Option 2: In this also fusion reaction occurs and the nuclei is heavier than Helium which is Neon.
Option 3 and Option 4: These two reactions are nuclear fission reactions of Uranium-235 because one heavier element is breaking into more than 2 products.
Hence, the correct option is 2.
