Options is 1 and 2 means A) is correct because when to ascending grade meet if G1>G2 then valleys curve form and if G2>G1 then summit curve form likewise if descending grade meets with another descending grade if G1>G2 valley curve but G2>G1 summit curve form.
So both 1 and 2 are correct but 3 is wrong.
