Both primary and secondary cells serve the purpose of supplying energy to external circuit. Chemical reactions are reversible and cell is rechargeable for only secondary cells.  Strength of current in primary cell is low and in secondary cell can be high or low.

Primary cells are light and cheap. All other options apply to secondary cell.

Primary cells are use and throw. They are not recyclable since structure is carefully packed. They are not rechargable since chemical reactions involved are not recyclable. 

Primary cells have high internal resistance while secondary cells have low internal resistance.

Secondary cells are also called accumulators.

Dry cell have a typical voltage of around 1.1 Volts.They become inadequate for use with time because their internal resistance increases many fold.

Commonly used cell is dry cell.

The current capacity of the charged secondary cell does not depend on temperature. so if the temperature is increased or decreased there is no any change in current capacity of any secondary cell, hence option C is correct.

A primary cell cannot be charged whereas secondary and electrochemical cell can be recharged.charging of a cell depends upon cell reaction is either reversible or irreversible . when reaction is irreversible then cell can not be charge after one time discharge.

In a series connection the positive terminal of the first battery is connected to the negative terminal of the second battery.

Both cell and battery store the chemical energy and then transforms the stored chemical energy to electrical energy. But cell is a single unit with positive and negative terminal whereas battery is a combination of cells connected end to end i.e. positive  to negative terminal.

While making a battery, negative end of battery is connected to positive terminal of other cell and so on.
