ℵ0\aleph_0ℵ0, the cardinality of the set of natural numbers N\mathbb{N}N (or alternatively, of the set of integers Z\mathbb{Z}Z).
c\mathfrak{c}c, the cardinality of the set of real numbers R\mathbb{R}R (or alternatively, of the power set 2N2^{ \mathbb{N}}2N).
2c2^\mathfrak{c}2c, the cardinality of the power set 2R2^{ \mathbb{R}}2R of R\mathbb{R}R.
None of the above.
