How to represent multiple conditions in a shell if statement?

I want to represent multiple conditions like this: if [ ( $g -eq 1 -a "$c" = "123" ) -o ( $g -eq 2 -a "$c" = "456" ) ] then echo abc; else echo efg; fi but when I execute the script, it shows syntax error at line 15: `[' unexpected, where line 15 is the one showing if .... What is wrong with this condition? I guess something is wrong with the `()`.
