Solution
The correct option is A alkoxy group
In IUPAC nomenclature of ethers, a hydrogen atom is replaced by −OR (alkoxy group) or −OAr (aryloxy group)
Example: CH3−O−CH3 is an ether which is obtained by replacing one hydrogen atom from methane with methoxy group (−OCH3). Thus, the ether will be named as methoxymethane.
