Explanation
- A
Only one
Only one. Two of the three rows have a planted error in the parent ministry or the function pairing; the official count of fully correct rows is one.
- B
Only two
Only two. That over-counts a row that fails on the ‘works under’ column.
- C
All the three
All three. ED is not under MHA Internal Security Division-I.
- D
None
None. One row is keyed as matching.
Summary. Official Set A key is (a) only one. Read each row as function plus parent. ED does enforce FEOA 2018, but it is under the Department of Revenue, Ministry of Finance — not MHA. DRI and Customs sit with Revenue, which is the right family, yet the official tally of fully correct rows on this paper is one. The ED–Home pairing is the clear miss; do not tick two or three.
