Solution

The correct option is A alkoxy group
In IUPAC nomenclature of ethers, a hydrogen atom is replaced by $- O R$ (alkoxy group) or $- O A r$ (aryloxy group)
Example: $C H_{3} - O - C H_{3}$ is an ether which is obtained by replacing one hydrogen atom from methane with methoxy group ( $- O C H_{3}$ ). Thus, the ether will be named as methoxymethane.
