D. 16 bytes
Answer: Option A
Solution(By Examveda Team)
The correct answer is Option A: 4 bytes.In Java, a float variable is a single-precision floating-point data type that occupies 4 bytes of memory.
Here's the breakdown:
Option A: 4 bytes - This is the correct size of a float variable in Java, which is a single-precision floating-point type.
Option B: 8 bytes - This size is associated with the double data type, not float. double is a double-precision floating-point type.
Option C: 2 bytes - This size is associated with the char data type, not float. char represents Unicode characters.
Option D: 16 bytes - This size is not standard for any primitive data type in Java.
So, the size of a float variable in Java is 4 bytes.
