A, B, C are correct. Anyone explain why answer is (C)?

Sumit said: (Jul 12, 2016)  
B is wrong because no arrow sign. A and C is correct. But C gives both activity and time. So more accurate is c.

Abdul Samad said: (Dec 10, 2016)  
C is correct, it gives both the information.

Activities are shown by arrows only. There is no arrow shown here. So, option D is the right answer.

Ravi said: (Mar 6, 2018)  
Thanks for the right information @Sumit.

Thanks @Sumit.

Muhammad Atiq said: (Oct 22, 2018)  
But how it take 8 units of time?

Can anyone explain this?

The digit written on an arrow represents the time required to complete that activity.

Bastenga said: (Jul 28, 2019)  
Right, Thanks @Sumit.

Dinesh said: (Jul 10, 2020)  
D is the correct answer. Because, Arrow indicates activity. Here no arrow, so no activity.

Shubham Anadkat said: (Jun 10, 2021)  
"Excavation Of Footing" indicates the Activity. So here no matter there is an arrow or not.

So according to me option C fulfill all criteria.

Deepankar said: (Aug 9, 2021)  
B is wrong because there is no arrow-head that would tell which is a head event and which is tail event.

A is true but C gives more detail in addition to A. Thatss why it is preferred over A.
