Let $(L,\leq)$ be a lattice. Then for all $x,y,z\in L$ which of the following is FALSE?

$(A).x\lor y = y\lor x$

$(B).x\lor (x\land y) = x$

$(C).x\lor (y\land z) = (x\lor y)\land(x\lor z)$

$(D).x\land (x\lor y) = x$

Here $\leq$ represents any relation, Not less than or eqal to specifically. Lattice might not satisfy distributive property so Option C is false.

{L,<=} is tos and all tos is always distribute lattic.

And all lattice follow Identity property , associative,commutative, absorption

But not distributed property if a lattice follow distributed property than this type of lattice called distributed lattice.

Here given lattice is tos and tos always follow all these propertie so I think all option are wrong.

Please correct me if my statement is wrong.

why a lattice will follow C?
you are absolutely correct. i too have same dilemma. i think all options are correct
