Equivalent resistance for resistors in series:

Req=R1+R2+...+Rn

Equivalent resistance for resistors in parallel:

1Req=1R1+1R2+...+1Rn

For the series connection, the equivalent resistance increases as more resistors are being added.

Let's consider the option a).

The flow of current is the same through the resistors that are connected in series in a circuit.
