Answer 1

Explanation :

The following code will give an error.

We have defined variables 'X1' in line 1 & 'Xinv1' in line 2 but variables 'Xinv2' & 'X2' is not defined.

So, when the execution reaches line 3 : Xinvinv = Xinv2*X2 , it will result in an error : Undefined function or variable 'Xinv2'.

Hence ,

Answer : (b) error
