Explanation:

- Option 1: Taking pads almost valueless from a tree on government waste land can be considered trivial or insignificant, especially if the value of the items taken is minimal. Such cases often fall under the doctrine of "de minimis" under Section 95 of the Indian Penal Code (IPC), which overlooks negligible acts.

- Option 2: Dipping a pen in another man's inkpot reflects a minor impropriety in social conduct. Given its trivial nature, this action is likely to be overlooked under Section 95 IPC, treating it as an inconsequential act.

- Option 3: Both (a) and (b) could be seen as trifles under Section 95 IPC due to their minimal impact and lack of harm or intent.

- Option 4: None of the above suggest that neither action falls under trifle consideration, which is less likely given the nature of the acts.

Answer: Option 3: Both (a) and (b).
