Question

Which of the following is true? *
{1,2}⊂{1,{2},3}
{2,{1}}⊂{1,{2},3}
{2}⊂{1,{2},3}
{1,{2}}⊂{1,{2},3}​

Answer 1

Answer:

{2}c{1{2}3}

Step-by-step explanation:

I think this is the correct answer.

Answer 2

Option(d) is the correct answer.

We are talking about subsets, ⊂ which represent subsets. so, we have to find which option correctly states the correct subset.

{1,{2}}⊂{1,{2},3}​, here 1, {2} is present in the main set given on the right hand side. therefore, ⊂ is correctly used in option(d).

Option(a), 2 is present as a set in the main set but as an element in the subset. Therefore it is not the right answer.

Option(b), {1} is present as a set in the subset, but as an element in the main set. Therefore it is not the right answer.

Option(c), 2 is an element in the subset but a set in the main set. Therefore it is not the right answer.
