• A. (a)-(i), (b)-(iii), (c)-(iv), (d)-(ii)
• B. (a)-(iv), (b)-(ii), (c)-(i), (d)-(iii)
• C. (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)
• D. (a)-(iv), (b)-(i), (c)-(iii), (d)-(ii)

Answer 1

The correct option is C (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)

Tetravalency is the ability of carbon to bond with carbon or 4 other monovalent atoms or two other divalent atoms. Overall carbon should form 4 bonds.
Catenation is the linkage of atoms of the same element to form long chains of compounds. Carbon shows the property of catenation because of its tetravalency.
Saturated hydrocarbons are the hydrocarbons with just single bonds throughout its compounds.
Unsaturated hydrocarbons are those hydrocarbon compounds which has double or triple bond in them.
