Sub-structure in module category of Virasoro vertex operator algebras $L(c_{p,q}, 0)$

We determine all premodular subcategories and modular tensor subcategories in the module categories of Virasoro vertex operator algebras $L(c_{p,q},0)$ and the module categories of the simple current extensions of $L(c_{p,p+1},0)$.
