Hint: Let us begin by the simple understanding that the capacity of a storage cell is the amount of charge available. It is expressed in ampere-hour. It is also measured in Kilowatt hour.

Complete Step By Step Answer:
A battery is a galvanic cell which consists of one or more cells that convert electrical energy into chemical energy. Redox reaction takes place inside the galvanic cell which can act as the source of chemical energy.
A battery has an anode and a cathode. Anode is considered as the positive side and cathode is considered as the negative side. In the galvanic cell electrons rush towards the positive anode, since electrons carry a negative charge anode is negatively charged and the protons rush toward the cathode making it positively charged.
There are mainly two different types of battery. Primary and secondary.
Primary cell: In these types of cells redox reactions can proceed only in one direction. The reactants inside the battery will keep on getting consumed as the time proceeds. They cannot be reused. One of the common examples are the batteries of household TV remotes.
Secondary cell: These are the type of batteries which can be recharged by passing current through electrodes in the opposite direction. Lead storage batteries are an example. It is used in inverters and automobiles. It consists of lead anode and cathode is lead grid packed with lead dioxide.

So the correct answer is Option B

Another classification of batteries based on application are Household batteries, these are the batteries which are used in our daily life for example Nickel-Cadmium batteries. Industrial batteries are those which are built for heavy duty requirements. Wet Nickel Cadmium is an example. Vehicle batteries are specially made batteries to power cars, bikes etc. Lead-acid battery is an example.
