Several resistors are connected in series. which of the following statements is correct? choose all that are correct.

If the choices were;
The equivalent resistance is greater than any of the resistance in group
The equivalent resistance is less than any of the resistance in the group
The equivalent resistance is less than any of the resistance in the group 
The equivalent resistance is equal to the sum of the resistances in the group 
None of the statement is correct.

I believe out of the above statement; the correct statement is , The equivalent resistance is equal to the sum of the resistances in the group.
When resistors are in series, the current is the same through each resistor. The total resistance of the circuit is found by simply adding up the resistance values of the individual resistors; Equivalent resistance of resistors in series : R= R1 +R2+ R3 +
