Answer :

H

Explanation:

* is a dereference operator & is a reference operator. They
can be applied any number of times provided it is
meaningful. Here p points to the first character in the
string "Hello". *p dereferences it and so its value is H.
Again & references it to an address and * dereferences it
to the value H.
