C = correct. String is immutable so trim will not do anything. Also, the string is not empty, Java will reserve space in the heap.
Answer: C
package q070;
public class Test {
public static void main(String[] args) {
String str = ” “;
str.trim();
System.out.println(str.equals(“”) +” “+ str.isEmpty());
}
}
/*Output
false false
*/
C
