The answer is "Option a"

Explanation:

Range-based for loop performs a sequence for a loop. It's more accessible as the conventional loop, for example, all components in the array, running more than a range of possibilities. In the given question "option a" is correct because it follows the correct syntax and other choices were wrong, which can be described as follows:

In option b, It's not correct, because in this code the range declaration is wrong. In option c, It is wrong, because in this code the datatype is missing. In option d, It is illegal syntax, that's why it is wrong.
