Explanation:

Let’s break this down:

- U # F: U is equal to F.

- F $ W: F is not smaller than W, so F = W.

- W - K: W is greater than K, so W > K.

Now, let’s connect the dots:

- Since U = F and F = W, U = W.

- Since W > K, that means U (which is at least as big as W) could also be bigger than K, but not always (it could be equal if F = W and U = F).

- So U could be > K or = K, but not necessarily.

Let’s check the conclusions:

1. K $ U (K not smaller than U, so K = U): Not always true. U can be greater than K.

2. K # U (K is equal to U): Not always true either.

3. W @ U (W neither greater than nor equal to U ? W < U): This is not necessarily true, because U = W, but not strictly greater.

So, none of the conclusions definitely follow.

Correct option: 4, None follows
