Identify the logical/Boolean statement:

1. 15+4=19
2. I want to have coffee.
3. Should I wear the mask or not?
4. I love dogs.

The boolean expression of the following logic circuit is:

1. (A+B).C'+B
2. A'B'+C+B'A
3. A.B.C+(B'+C').A
4. A+B+C'(A+B)

Assertion (A): Data is stored inside a computer in the form of 0s and 1s.

Reasoning (R): Number system is a technique of representing numbers in different forms.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

Assertion (A): The base/radix of binary number system is 2.

Reasoning (R): Binary number system has only two digits, i.e., 1 and 0.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.
