Where is the error, if any, in the following program? Assume `numA` and `numB` have values. Also assume the indenting is correct.

```
if numA = numB: # line 1
numX = numA # line 2
elif numA > numB: # line 3
numX = B # line 4
```

A. line 1
B. line 2
C. line 3
D. line 4



Answer :

Let's go through each line of the program step-by-step to identify any errors:

### Line 1: `if num A=numB:`
- The error here is that the assignment operator `=` is used instead of the equality operator `==`.
- Corrected: `if numA == numB:`

### Line 2: `num X=num A`
- The issue in this line is that variable names should not contain spaces.
- Corrected: `numX = numA`

### Line 3: `elif num A>numB:`
- Similar to Line 1, variable names should not contain spaces.
- Corrected: `elif numA > numB:`

### Line 4: `num X=B`
- The error here is that `B` is not defined. It should be `numB`.
- Corrected: `numX = numB`

### Summary of Errors:
- Line 1: Incorrect usage of the assignment operator instead of the equality operator.
- Line 2 & 3: Spaces in variable names.
- Line 4: Undefined variable `B`.

### Corrected Code:
The corrected code should look like this:
```python
if numA == numB:
numX = numA
elif numA > numB:
numX = numB
```

In conclusion, the error is in line 1. This line should use an equality operator `==` instead of an assignment operator `=`. Other lines also have errors related to variable names and undefined variables, but the primary error by the given multiple-choice options is identified in line 1.
