Detailed Technical Solution & Explanation
Let us verify each proposition in CPM event-oriented network analysis:
•
Statement (i): An activity cannot start until its tail event occurs. Therefore, Earliest Start Time () equals the Early Event Time of node (). Correct.
•
Statement (ii): An activity must finish by the time head event occurs. Therefore, Latest Finish Time () equals the Late Event Time of node (). Correct.
•
Statement (iii): By definition, Latest Start Time equals Latest Finish Time minus activity duration (). Correct.
Since all three statements are fundamentally correct, none of them are incorrect.
Option Analysis:
•
Option A (Only (i)): Incorrect; statement (i) is correct.
•
Option B ((i) and (ii)): Incorrect; both statements (i) and (ii) are correct.
•
Option C ((ii) and (iii)): Incorrect; both statements (ii) and (iii) are correct.
•
Option D (None): Correct; none of the given statements are incorrect.
