Image 1:
8,9,10,11
Option C is correct.
Image 2:
No of subsets= 16
Step-by-step explanation:
Image 1:
We need to list the elements of the set:
{x | x ∈ Integers and 8 ≤ x < 12}
The values of x are between 8 and 12, where 8 is included because we have less than equal to, but 12 is not included because x is less than 12.
So, elements will be:
8,9,10,11
Option C is correct.

<u>Subsets</u>
If there are n elements in the set, then there are 2ⁿ elements
We have set:
B={car,train,bus,plane}
No of elements in set = 4
No of subsets= 2⁴ = 16
No of subsets= 16
The subsets are:
{{},{car},{train},{bus},{plane},{car,train},{car,bus},{car,plane},{train,bus},{train,plane},{bus,plane},{car,train,bus},{car,train,plane},{car,bus,plane},{train,bus,plane},{car,train,bus,plane}}
