Why is not correct C ?
Because B only print all elements (without delimiters) which pass the condition
System.out.println("1."+fruits.stream().filter(f -> f.contains("n")).findAny().get());
fruits.stream().filter(f -> f.contains("n")).forEachOrdered(System.out::print);
System.out.println("\n3."+fruits.stream().filter(f -> f.contains("n")).findFirst ());
System.out.println("4."+fruits.stream().anyMatch(f -> f.contains("n")));
