Explanation:

First statement is incorrect and the statement should read as when a cyclone approaches there is a fall in the barometric reading, while an anticyclone causes barometric reading to rise.

Second statement is correct as closer the isobars are together the stronger the winds are. Isobars are always much closer together in a depression compared with an anticyclone.

Third statement is incorrect as in northern hemisphere cyclonic circulation is counter-clockwise, while anti-cyclonic circulation is counter-clock-wise in southern hemisphere.
