Answer 1

Explanation:

2 is the correct answer...

Valency of carbon is always 4 because it needed 4 more electron to complete its octate . Hence valency is always fix of any element . If you are asking about oxidation state of these compounds then in cH4 oxidation state of carbon is 4 , in C2H6 it is 3 and in C2H4 it is 2 .
