To print "tofu" to the console from the `proteinChoices` array, you need to access the element at the corresponding index. In the provided array, "tofu" is at index 3.
The correct line of code that prints "tofu" is:
```javascript
console.log(proteinChoices[3]);
```
The other options are incorrect for the following reasons:
1. `console(proteinChoices[4]);` - This will cause an error because `console` is not a function.
2. `console.log[proteinChoices(3)];` - This is incorrect because it uses the bracket notation incorrectly and attempts to call `proteinChoices` as a function.
3. `console[proteinChoices(4)];` - This is also incorrect because it attempts to call `proteinChoices` as a function and uses bracket notation improperly.
The only valid line that will output "tofu" is the first one:
```javascript
console.log(proteinChoices[3]);
```
