Which of the following will delete key-value pair for key = "Red" from a dictionary D1 ?

1. delete D1("Red")
2. del.D1("Red")
3. del D1["Red"]
4. del D1

What will be the output?

D1 = { "Rahul":56, "Virat":99} 
print("virat" in D1)

1. True
2. False
3. No output
4. Error

Assertion (A): Tuple in Python is an ordered and immutable data type.

Reasoning (R): Tuples can contain heterogenous data and permit duplicate values as well.

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.

Consider the given two statements:

Statement 1: t1 = tuple('python')
Statement 2: t1[4] = 'z'

Assertion (A): The above code will generate an error.

Reasoning (R): Tuple is immutable by nature.

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.
