Which of the following statements are correct?
a) If A is a bounded subset of the real line, every infinite subset of A has a limit point.
b) If A is a bounded subset of the real line, every open cover of A has a finite subcover.
c) If A is an infinite open subset of the real line, there is an infinite open cover with a finite subcover.
d) If A is a closed subset of the real line, every open cover of A has a finite subcover.
Just chose the correct answer choice.
