Find the correct answer based on the number of minimum carbons required for alkyne to show the corresponding isomerism

          

Isomerism	Minimum number of carbons required
(i) Chain isomerism	(a) 2
(ii) Positional isomerism	(b) 3
(iii) Functional isomerism	(c) 4
(iv) Ring chain isomerism	(d) 5
(v) Optical isomerism	(e) 6

• A

  (i)–(a); (ii)–(b); (iii)–(c); (iv)–(d); (v)–(e)

       

• B

   (i)–(d); (ii)–(c); (iii)–(b); (iv)–(b); (v)–(e)

• C

   (i)–(d); (ii)–(c); (iii)–(b); (iv)–(a); (v)–(e)

• D

   (i)–(d); (ii)–(c); (iii)–(a); (iv)–(b); (v)–(e)
