Answer:
ITS [tex]C_{4}H_{10}[/tex] AND [tex]C_{5}H_{12}[/tex]
_____________________________________
GENERAL FORMULA OF ALKANE
[tex]C_{n}H_{2n+2}[/tex]
Where n is the number of CARBONS
_____________________________________
A)
By using the General Formula of Alkanes having 4 carbon atoms is
[tex]C_{4}H_{2x4+2}[/tex]
[tex]C_{4}H_{10}[/tex]
C)
By using the General Formula of Alkanes having 5 carbon atoms is
[tex]C_{5}H_{2x5+2}[/tex]
[tex]C_{5}H_{12}[/tex]
_____________________________________
IF YOU USE THE SAME FORMULA FOR THE OTHER TWO OPTIONS THE OUTCOME WILL NOT BE AS SAME AS GIVEN IN THE QUESTION SO THOSE TWO ARE CAN NOT BE OUR ANSWER

HOPE THIS HELPS!
