Which of the following is true about LR grammar? LR (K) grammar is det...

LR(k) grammars are the subclasses of context free grammars. If G₁ is an LR(k) grammar then there must be a deterministic pushdown automata that accepts L(G₁). So, LR(k) grammar is a deterministic context free grammar.
If G₁ is an LR(k) grammar where k>1, then there must be an equivalent grammar G₂ which is LR(1). Therefore, statement 2 is also true.
In LR(k) grammars L stands for the left to right scanning of the input strings and 'R' denotes the rightmost derivation and k is the number of look ahead input symbols.
To get a right derivation tree for the given sentence 's' , we can start with s and replace it with a substring s₁ and repeat the process until we get the same start symbol.
