Answer:
Option A is the correct answer for the above question.
Explanation:
A Victim is a person, who faces the problem of a criminal person. Here in the question, the scenario is that a user is a victim of the identity of being theft by some other person. So the user can get known by the help of option a, which suggests that the user's credit card report display something which is not done by him then it can be the scenario, where the user can understand that he is a victim. hence option a is the correct answer where the other option is not because--
- Option B suggests the user does not pay the bill on time but it is a general case because the bill is paid by the user is in every month not a single time.
- Option C suggests both options (A and B) are correct, but option b is not the correct.
- Option D suggests that no option is valid from the above but option A is the correct.
Answer:
b. foreign key
Explanation:
In the database world, a foreign key is a field on one table and a primary key for another table. The purpose of a foreign key is to provide linkages between two or more tables. Given two tables A and B, and making A the point of reference, a primary key is a field that is unique in A while a foreign key is unique in B.
On another hand, a composite primary key is a combination of two or more fields/columns on database table that can be used to uniquely identify each row in the table.
In the database lingua, what we have is a unique key not a distinct key, though the two words are similar in meaning.
A duplicate key is used when an information may be repeatedly entered on a table.
So the correct option is a foreign key.
Answer: True
Explanation:Orthogonal instruction set is the set of instruction that can use can use all addressing mode. They have independent working and so instruction can use any register the prefer and this leads to overlapping in instruction and complexity.
When RISC architecture got introduced ,it got more preference due to reduced instruction and less complexity as compared to orthogonal instruction.So it not considered elegant to have more orthogonal instruction.
CAD provides the architect opportunity to electronically plan and place elements of a building. The correct option among all the options that are given in the question is option "c". The full form of CAD is Computer Aided Design. It gives the designers the opportunity to create three dimensional pictures.
