[B].

[C].

[D].

Answer: Option A

There is an increase in foreign exchange reserves during the years 1992 – 1993, 1994 – 1995, 1996 – 1997, 1997 – 1998 as compared to previous year (as shown by bar-graph).

The percentage increase in reserves during these years compared to previous year are:

For 1992 – 1993 =		(3720 – 2640)	x 100		% = 40.91%.
		2640

For 1994 – 1995 =		(3360 – 2520)	x 100		% = 33.33%.
		2520

For 1996 – 1997 =		(4320 – 3120)	x 100		% = 38.46%.
		3120

For 1997 – 1998 =		(5040 – 4320)	x 100		% = 16.67%.
		4320

Clearly, the percentage increase over previous year is highest for 1992 – 1993.

= 82.35% < 83.33% and 83.33% > 80%
