In parallel resistance the effective resistance value will be less than the smallest valued resistance. For eg, if a 2 ohm and 3 ohm resistance are in parallel effective resistance will be less than 2 ohm. So when one is opened the effective resistance increases.

Can you give me the proper explanation? I want correct answer.

As we know for a particular resistor in series net resistance is greater than a resistance in parallel if we remove resistor of one of them from a parallel circuit the net result will increases as reverse as in series.

If we consider the two resistance in parallel, r1 &r2, So according law R1*R2/ (R1+R2). If one of them is open means R1=NO, So it will be R2 in Series. So total resistance will decrease.

According to the parallel resistance circuit the equivalent resistance is given by RT=R1||R2= (R1*R2)/(R2+R2. That answer will be less compare with when any one resistance open, because the total resistance is equalto RT=R1 or R2 only. So RT is increases.
