Free float for any project activity is defined as the difference between:

Question

Accepted Answer

Its earliest finish time and earliest start time for its successor activity. Free float represents the surplus duration available for an activity such that its completion does not delay the earliest possible start of any succeeding activity. Mathematically:
$$FF_{i-j} = E_j - E_i - t_{ij} = ES_{	ext{successor}} - EF_{i-j}$$
Where $ES_{	ext{successor}}$ is the earliest start time of the succeeding activity and $EF_{i-j}$ is the earliest finish time of the current activity.

### Option Analysis:
- Option A (Its latest start time and earliest start time): Defines Total Float ($TF = LS - ES$).
- Option B (Its earliest finish time and earliest start time for its successor activity): Correct; precisely describes Free Float.
- Option C (Its latest finish time and earliest start time for its successor activity): Erroneous combination.
- Option D (Its earliest finish time and latest start time for its successor activity): Erroneous combination.
