Correct answer is A.
Since an activity with float will not affect the project duration as long as any delay is not greater than the float, choice B could not be best. Choice D cannot be best as this situation is not related to scope, just time. An activity with free float means it has time where it can be delayed without impacting the next activity. Therefore, choice C cannot be best. Any delay in when an activity is to be completed will most likely impact resources schedules.
