The easiest way to find the number that makes the statement true is to substitute the given answers into the equation.

so

Part 1)

a) For

-----> is false

b) For

-----> is false

c) For

-----> is false

d) For

-----> is true

therefore

the answer part 1) is the option D

Part 2)

a) For

----> is false

b) For

----> is false

c) For

----> is false

d) For

----> is True

therefore

the answer Part 2) is the option D

Part 3)

we have

For

we know that

therefore

the answer Part 3)  is the option B

Part 4)

we have

For

we know that

therefore

the answer Part 4)  is the option B
