I want to ask, why here (see the pic)
[tex]1 \notin C[/tex]
?
And why it is that if
[tex]A \in B[/tex]
and
[tex]B \subset C[/tex]
, then why not
[tex]A \nsubseteq C [/tex]
??
I am asking this question third time, please anyone Brainly Aryabhatta answer this.

Here A is not subset of C because 1 is an element of A but not of C
Note that {1} is an element of C its not 1 it is {1}
Hope you understand
