A Correct answer
Explanation

The comma operator in C/C++/Java has the lowest precedence of all operators and evaluates left-to-right. The answer is A because the comma operator is at the bottom of the precedence hierarchy - it executes after all other operations. Left-to-right grouping means expressions are evaluated in order (a, b, c evaluates a, then b, then c, returning c's value). This is useful in for-loops and compact expressions.
