Hint: We have to know that diborane is a synthetic compound consisting of boron and hydrogen with the recipe ${B_2}{O_6}$ . It is a vapid, pyrophoric gas with an appallingly sweet scent. Equivalent words incorporate boro-ethane, boron hydride, and diboron hexahydride. Diborane is a key boron compound with an assortment of uses.

Complete answer:
We have to know that diborane is an exceptionally receptive and flexible reagent. Its ruling response design includes the development of adducts with Lewis bases. Regularly such introductory adducts continue quickly to give different items. It responds with alkali to frame the di-ammoniate of diborane, $DADB$ , with lesser amounts of smelling salts borane, contingent upon the conditions utilized. Diborane additionally responds promptly with alkynes to frame subbed alkene items, which promptly go through additional option responses.
As a pyrophoric substance, diborane responds exothermically with oxygen to shape boron trioxide and water, such a lot of that it was considered as a potential rocket or ramjet charge:
$2{B_2}{H_6} + 6{O_2} \to 2{B_2}{O_3} + 6{H_2}O$

Therefore, the correct answer is (B) ${B_2}{O_3}$ .

Additional information:
We have to see, diborane likewise responds fiercely with water to frame hydrogen and boric corrosive:
${B_2}{H_6} + 6{H_2}O \to 2B{(OH)_3} + 6{H_2}$
We have to see, diborane likewise responds with methanol to give hydrogen and tri-methoxyborate ester:
${B_2}{H_6} + 6MeOH \to 2B{(OMe)_3} + 6{H_2}$

We have to know that diborane and its variations are focal natural combination reagents for hydroboration. Alkenes add across the $B - H$ securities to give trialkyl boranes, which can be additionally expounded. Diborane is utilized as a lessening specialist generally correlative to the reactivity of lithium aluminum hydride.
