Step 1: What are we asked?
We need the main subject matter of Shakespearean tragedy. We will test each choice against well known plays.
Step 2: Use famous examples.
Take Hamlet, Macbeth and Othello. In each, the story turns on a choice the hero makes while troubled in mind: Hamlet delays, Macbeth murders the king, Othello believes Iago.
Step 3: Measure the options against these plays.
Option (1) says fate alone, but the heroes act freely. Option (2) says supernatural only, but ghosts and witches are just a spark. Option (4) says social realism, a style that came much later. Option (3), inner conflict and moral dilemma, fits every one of the plays.
Step 4: Conclude.
Only one option describes what these plays share: the hero struggles with his own conscience and choices.
Final Answer:
The best match is inner conflict and moral dilemma, option (3).
\[ \boxed{\text{3}} \]
