Explanation:

Let's analyze the clues step by step:

- Months: January, February, March, April, May, June, July, August

- G is born in a 31-day month (Jan, Mar, May, Jul, Aug), not May.

- One month gap between G and A, A after G.

- B is born in February (least days).

- E is immediately after C.

- Number before E is one more than those after E ? E must be 5th (as 4 before, 3 after).

- F born before D.

- Gap of two months between A and H.

Let’s place E as 5th; so:

1. __

2. __

3. __

4. C

5. E

6. __

7. __

8. __

Now, let's build:

- February is B (must be 2nd or 3rd to place C before E). If B is 2nd (Feb), then Jan is 1st. Let's try this:

1. __

2. B (Feb)

3. __

4. C

5. E

6. __

7. __

8. __

C is before E, so let’s tentatively keep this.

Now, G is in a 31-day month, not May. Options: January (if Jan=1), March (could be 3), July (7), August (8).

Try G in March (3rd), since Jan and Feb taken.

- There’s a gap of one month between G and A, and A is after G. So, if G = Mar (3), A must be 5th (May).

- But 5th is E. So, not Mar.

Try G in July (7):

- Then, A can be 8th (August). There is a gap of one month, and A comes after G.

So working so:

1. __ (Jan)

2. B (Feb)

3. __ (Mar)

4. C (Apr)

5. E (May)

6. __ (Jun)

7. G (Jul)

8. A (Aug)

Now, E is 5th, so 4 persons before E.

How many persons born before C? C is 4th, so 3 persons are before C: 1st, 2nd, 3rd.

Option 3: Three

Summary of statements:

- G - July (31 days), not May.

- Gap of 1 month between G (July) and A (August) and A after G.

- B - February (least days, 2nd).

- E after C. C is 4th, E is 5th.

- 4 people before E, 3 after (so E is 5th).

- F is before D (not placed here, but doesn't impact C's position).

- Gap of two months between A (Aug) and H (must be 5th and 8th or 6th and 8th).

- C's position: 4th ? 3 persons before.

Correct Option:

- Option 3: Three
