Given that the day before yesterday was Friday.
Let the current day be represented as Day 0.
Day before yesterday (Day -2) = Friday
Yesterday (Day -1) = Saturday
Today (Day 0) = Sunday
Tomorrow (Day +1) = Monday
Day after tomorrow (Day +2) = Tuesday
The question asks when Tuesday will occur relative to today.
From the timeline established above, Tuesday occurs on Day +2, which is the day after tomorrow.
Checking each option:
Option 1: A day after tomorrow = Day +2 = Tuesday ✓
Option 2: Tomorrow = Day +1 = Monday
Option 3: Today = Day 0 = Sunday
Option 4: 3rd day after today = Day +3 = Wednesday
Therefore, Tuesday will be a day after tomorrow.
The answer is Option 1.
