The correct option is B. To increase the production of ammonia, you have to increase the pressure of the system. Increase in pressure will result in increased production of ammonia because this will drive the chemical reaction forward.
When we apply pressure or increase the pressure then molecules of the gas come closer to each other. As a result, forces of attraction will increase which will lead to increase in production of the product.
Therefore, in the given reaction the production can be increased by increasing the pressure of the system.
Battery casing is manufactured in layers. The casing layers are developed from various raw materials and can include one or two, for example, polyethylene terephthalate layers, a polymer layer, and a polypropylene layer.
