Is Sriya and Deepti are part of a team of four, it means that two boys have to be selected. Since Sriya is selected therefore Sood will be definitely selected. Now , the second boy can be either Amit or Gupta. Therefore, the answer cannot be determined.

The earliest day on which rolling can happen is after both the filling activities have been completed which can be done on the first two days.

The activity on Thursday can be any of the three mentioned activities which may be performed by any one of P, Q, R and or S and so the correct answer cannot be determined.

If P works on the second day, P must have done filling since rolling cannot be done on the second day, that is, before both the filling activities are completed. Since watering is done on Thursday, the activity on Wednesday must be rolling.

The activities during the week can be scheduled in the following three different ways:
(i) Filling, Watering , Filling, Rolling, Watering, Rolling

Since swing is practiced on Wednesday and putt on Thursday, swing will be practiced on Wednesday afternoon. Also, plan and stance both have to be practiced in the afternoon. Therefore, the aspects practiced in the morning will be putt, push and drive.

The aspect practiced on Thursday morning cannot be putt, plan stance or drive. Therefore, the aspect practiced on Thursday morning must be push.

Plan

If putt has to be practiced on Friday, it has to be Friday afternoon. Plan has to be practiced on Wednesday afternoon and stance on Thursday afternoon. Since putt is practiced on Friday, stance cannot be practiced on Thursday morning. So, stance has to be practiced on Wednesday morning and push on Thursday morning.

This combination is not acceptable since it is given that Sri Lanka and Germany cannot be selected together.
