The image you uploaded is the same as the previous one, showing a multiple-choice question about functions. After reviewing the options again, my previous answer remains the same.

Question Recap:

You are asked to identify which set of ordered pairs represents a function from set $A = \{1, 2, 3, 4\}$ to set $B = \{p, q, r, s\}$. A function is valid if each element of $A$ is paired with exactly one element from $B$.

  • Invalid: Element 4 from set $A$ is missing.

• Option b: [ \
