Given below is a cause followed by possible effects numbered I, II and III. Read the cause carefully and decide which of the three can be a/the possible effect(s).

Cause:

There has been an increase in the number of thefts of bicycles being reported in the apartments in locality X in the last 2 months. Effects:

(I) Police have instructed security guards of locality X to record details of all entries and exits and verify the phone numbers of all delivery personnel.

(II) Many apartment complexes have decided to install multiple CCTV cameras inside and outside their gates.

(III) More women police constables have been appointed in the police station adjoining locality X.

Cause: There has been an increase in the number of thefts of bicycles being reported in the apartments in locality X in the last 2 months.

(I) Police have instructed security guards of locality X to record details of all entries and exits and verify the phone numbers of all delivery personnel.

The cause mentions an increase in bicycle thefts. To combat this, the police instructing security guards to record entries and exits, and verify delivery personnel's phone numbers, is a direct and logical response. This measure aims to increase surveillance and identify potential suspects or patterns.

Therefore, Effect I is a possible effect.

(II) Many apartment complexes have decided to install multiple CCTV cameras inside and outside their gates.

Installing CCTV cameras is a common security measure to deter and detect crime. The increase in bicycle thefts would naturally lead apartment complexes to enhance their security. Installing CCTV cameras inside and outside the gates would increase surveillance and help identify potential thieves.

Therefore, Effect II is a possible effect.

(III) More women police constables have been appointed in the police station adjoining locality X.

While increasing police presence can deter crime in general, the specific cause is bicycle thefts. Appointing more women police constables doesn't specifically address bicycle thefts. It's a general increase in police personnel, not a targeted response to the specific issue.

Therefore, Effect III is not a direct or logical effect of the given cause.

Thus, Effects I and II are possible effects of the given cause.

Hence, the correct answer is "Option 1".
