Solution
The correct option is ACO2.
The geometry of CO2 is linear. Therefore the bond angle is maximum 180o in it.
In H2O the central atom O has two lone pairs. The repulsion between lone pairs and lone pair-bond pair decreases the bond angle.
In CH4 there are 4H bonded to central C atom which are arranged in a tetrahedral position to minimize the repulsion between them therefore the bond angle is smaller than it is in CO2.
