Answer 1

> The term catenation deseribes the - ability of carbon atoms to form long chains and rings. self linking Process of an element is called catenation carbon shows maximum catenation lopty. valency of each carbon atom can be isfied by combining with other carbon atoms since carbon is smaul , thus the bond formed between two carbon atom is strong. There for shows maximum catenation . Satisfied by ith options are in correct so, the 1st, 2nd, 3rd, 5th options are in as they didd not describe the self linking process. soonly 4th option correet.
