how can A be true?? for all x ( 7p(x) v q(x) ) → for all x 7(p(x)) v for all x q(x) here left hand side can be true for all x, if either p(x) is false or q(x) is true for a particular x but for RHS either for all x p(x) has to false or for all x q(x) has to true so it shouldn’t be valid and i think B should be valid please confirm it ??? and tell me where m wrong??

Self Doubt: What is the strategy to color a graph with minimum colors?
I know the fact that if a graph has a complete subgraph, say Kn, at least n will be the chromatic number. But what is the strategy for coloring vertices of a graph so that we need minimum colors? Many times it has happened that the order in which I color leads to more number of colors.

Consider the set H of all 3 × 3 matrices of the type: $\begin{bmatrix} a&f&e\\ 0&b&d\\ 0&0&c\\ \end{bmatrix}$ where a, b, c, d, e and f are real numbers and $abc ≠ 0$. Under the matrix multiplication operation, the set H is: (a) a group (b) a monoid but not a group (c) a semigroup but not a monoid (d) neither a group nor a semigroup
