Answer:
The answer is: Only A is correct.
Explanation:
Variables in a program can assume different values at different times, and the program can then produce different results, depending on circumstances, so A is correct.
In a computer language, a reserved word (also known as a reserved identifier) is a word that cannot be used as an identifier, such as the name of a variable, function, or label – it is "reserved from use". This is a syntactic definition, and a reserved word may have no meaning. So, B is incorrect.
Hence, the answer is: Only A is correct.

Answer:
Chord is a set of rules for a peer-to-peer distributed hash table it collects key-value sets by allotting keys to several computers (known as "nodes"); a node will collect the values for all the keys for which that is reliable. Chord defines how keys are allocated to the nodes, and how a node can determine the value for a distributed key by first locating the node liable for such key.
Explanation:
A chord is a peer-to-peer lookup service. It Resolves the difficulty of establishing a data item in a combination of shared nodes, considering various node arrivals and removals The most crucial operation in most peer-to-peer method is the efficient position of data objects.
It is able of supporting only one operation i.e. given a key, it maps the key on a link.
Algorithm:
Algorithm shows working of the chord:
// x is a node used to find successor of id
x.find_successor(id)
if (id (x; successor])
return successor;
else
// query is being delivered around the circle
entrance successor.find_successor(id);
