Answer:
d. public myClass( ) {. . .}
Explanation:
A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.
Having said these about a constructor, a few other things are worth to be noted by a constructor.
i. In Java, a constructor has the same name as the name of its class.
For example, in the given class <em>myClass</em>, the constructor(s) should also have the name <em>myClass</em>.
ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:
<em>public void myClass(){...}</em>
This makes option a incorrect.
iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.
This makes option d a correct option.
Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.

Answer:
C. 2^16
Explanation:
In Computer Networking, there are five (5) classes of IP addresses, these include;
- Class A
- Class B
- Class C
- Class D
- Class E
The various classes of IP address are represented by the value of their first octet. The first octet value of Class B is 128-191 with a subnet mask of 16.
Hence, from the IP address 149.130.x.y where x and y are 8-bit numbers. The x and y equals 16-bit numbers.
Thus, 2^16 devices can connect to the Wellesley network before we run out of IP addresses.
