TRANSGRESSION: MORALITY::

The correct analogy is:

"Presumption : Propriety"

Here's why:

• Transgression refers to the act of violating a law or moral code.
• Presumption refers to overstepping bounds or taking liberties that might violate propriety (social norms or manners).

Both analogies compare an action that potentially violates a standard:

• Transgression violates morality.
• Presumption violates propriety.

Transgression is a violation of standard, conduct etc. that is considered good or right (morality) just like presumption violates standard proper behavior (propriety).
