Data type of variable a1 can be checked using: Answer choices Select only one option data(a1) type(a1) datatype(a1) None of the above
data(a1)
The correct answer is "type(a1)"
The correct way to check the data type of a variable a1 depends on the programming language you are using. However, in most programming languages, you can use the keyword "type" to check the data type of a variable.
For example, in Python, you can use the "type()" function. Here's an example:
```python
a1 = 42
print(type(a1))
```
This will output:
```
<class 'int'>
```
In this case, the data type of variable a1 is "int" (short for integer).
So, the correct answer to the question would be "type(a1)".
