Solution:
Given: 1 February 2020 was a Friday.
Now, from 1 February 2020 to 1 February 2030 = 10 Years.
In 10 Years, 3 Leap Year(2020, 2024, 2028) and 7 Ordinary Year.
So, the odd days in these 10 Years = (3 × 2) + (7 × 1)
→ 6 + 7 = 13 odd days.
And, 13 odd days = 13/7 = 1 week and 6 odd days.
So, 1 February 2030 was be Friday + 6 = Thursday.
Hence, the correct answer is "Option A".
