Since the value of the resistors is not given ,assuming that the fourth resistor R is connected in series with three more resistors the net resistance is R1+R2+R3+R4 = R+R+R+R =4R.
The 4th resistor added increases the resistance by one fourth.( if all the resistance are equal)
The 4th resistor added increases the resistance by one fourth.( if all the resistance are equal)

In a series connection, the total resistance is equal to the sum of all resistors as new resistor is added, resistance increases.
For example : if resistors are 1,2,3 ohms then total resistance is 6 ohms.
If 4 ohms is added then total becomes 10 ohms.

Suppose r1=1ohm, r2=2ohm, r3=3ohm.
Then we know in series R=r1+r2+r3.
i.e 1+2+3=6ohm.
Therefore by adding one more resistance it's resistance automatically increases as per in series circuit.

Suppose when three resistances are added together then the resistance value will increases, because we know that when they are connected in series then the result will be R=r1+r2+r3.

Obviously the resistance will increase because there's a series connection.
Answer won't be option A, because in series connection there be always addition not multiplication.

R1 = 6 ohm R2=4 ohm when these two are connected in series i.e. R1+R2=10 ohm so the value is gradually increase so like this the value of the fourth resistor is also increases.

The effective resistance in series is the sum of resistance. Therefore if a resistance is added in series,the overall resistance will increase. Answer-INCREASES

Because we know that,
R = R1+R2+R3+.......+Rn.
So if another resistor is connected in series then total resistance of the circuit will be increase.
R = R1+R2+R3+.......+Rn.
So if another resistor is connected in series then total resistance of the circuit will be increase.

When resistors are in the series connection, it's resistance are increased because the formula of the series connections is R=R1+R2+R3+....+Rn.

SUPPOSE,R1=5OHM, R2=6OHM R3=4OHM SO R4=?
IN SERIES, THE RESISTANCE IS 1/R,SO,
R1+R2+R3+R4=MORE THEN R1+R2+R3
SO, RESISTANCE IS INCREASE.
