What was one of the major theological concerns addressed in canto iv?
the problem of what would happen to infants who died unbaptized
the question of why non-christians would be sent to limbo
the best way to reform non-believers
the dilemma that prevents mortals from visiting the underworld

Option A.

Explanation:

The problem of what would happen to infants who died unbaptized , is the right answer.

Canto IV is a section of Inferno written by Dante Alighieri. It is lodged in Limbo, where noble non-Christians and unbaptized kids go. The central theme of the book is Justice. This theme makes a kind of sense because hell is where sinners persist to pay for those offences committed in living. However, there are nine categories of hell in the version of Dante.

One of the influential ecclesiastical concerns discussed in Canto IV is the predicament of what would happen to newborns who perished unbaptized.
