Bravais lattices are of (in $types$)

Which of the following crystals has the unit cell such that $a=b \neq c$ and $\alpha=\beta=90^{\circ}$,$\gamma=120^{\circ}$?

What is the total number of different types of unit cells present in the triclinic crystal system?

The crystal system with edge lengths $a \neq b \neq c$ and axial angles $\alpha = \beta = \gamma = 90^{\circ}$ is '$x$' and the number of Bravais lattices for it is '$y$'. $x$ and $y$ are:

Assertion : Graphite is an example of a tetragonal crystal system.
Reason : For a tetragonal system,$a = b \neq c$,$\alpha = \beta = 90^o$,$\gamma = 120^o$.

Which of the following is correct regarding crystal systems?
