Complete the following code snippet, which is intended to compress a hash code for an element x to become a valid array index:  
A)double h = x.hashCode(); 
B)double h = x.getHashCode(); 
C)int h = x.hashCode(); 
D)int h = x.getHashCode();

As array indexes are integers, we need to use an integer data type for the compressed hash code. Therefore, options A and B (which use double data type) are not correct. Option D is not correct either, as there is no method named getHashCode() in Java. The correct method is hashCode(), which returns an integer value. Hence, option C is the correct choice.
