Step-by-step explanation: Correct option is A ⊘ϵA B {⊘}ϵA D {7,⊘}⊂A a. ⊘ is present in A. So, ⊘∈A b. Another subset ⊘ is present in set A. So,⊘∈A c. 1 belongs to A, but not {1}. Hence {1} is not the subset of A d. 7 and ⊘ are present in A. ∴{7,⊘}⊂A Reply

Step-by-step explanation:
Correct option is
A
⊘ϵA
B
{⊘}ϵA
D
{7,⊘}⊂A
a. ⊘ is present in A. So, ⊘∈A
b. Another subset ⊘ is present in set A. So,⊘∈A
c. 1 belongs to A, but not {1}. Hence {1} is not the subset of A
d. 7 and ⊘ are present in A. ∴{7,⊘}⊂A
