The Correct answer is a positive commutative error.
Error =measured length - true length.
When the chain is too short ML >T. L.
SO, ERROR IS POSITIVE and it is commutative because every time we are using the same chain means we are adding.

If an elongated chain (suppose 2 metres too long) is kept on the ground. It will cover a distance of 32 metres but it will show you the 30-metre distance.

Answer C is correct because they already declared that the tape is 30 m but the distance measured is less than the tape length by 0.01m. Hence it is positive cumulative error.

Chain is too short i.e postive cumulative error.
Chain is too long i.e negative cumulative error.
So, the answer is postive cumulative.
Chain is too long i.e negative cumulative error.
So, the answer is postive cumulative.

Here short chain measure 30.01 meters.
So error =30.01-30=+0.01 hence answer is a positive cumulative error.
So error =30.01-30=+0.01 hence answer is a positive cumulative error.

Yes, you are right, Thanks @Vivek.

Answer is C, because if the length of the chain gets short then we measured less value. Because noted down more value.
So, an error will be cumulative positive in nature and correction will be negative.
So, an error will be cumulative positive in nature and correction will be negative.

The chain is 0.01 m short the true length of chain decrease to 29.99.
In the concept, chain length decrease passive error acts option C is right.

Answer c is correct.
If the chain is short then we will have much reading and thus measured length minus actual length will be a positive value.
And thus the answer is correct.

And thus the answer is correct.
