Step 1: Recall the hierarchy.
The taxonomic ladder from smallest to largest is Species, Genus, Family, Order, Class, Phylum, Kingdom.
Step 2: Understand ascending order.
Ascending means we start from the smallest unit (Species) and move up to the broadest (Kingdom).
Step 3: Note the letters given.
Species = g, Genus = a, Family = e, Order = c, Class = b, Phylum = d, Kingdom = f.
Step 4: Place them in order.
Following the ladder, the sequence becomes g, a, e, c, b, d, f.
Step 5: Compare with options.
Option 1, 3 and 4 break the ladder at some point, so they are wrong.
Step 6: Conclude.
Option 2 reads exactly (g),(a),(e),(c),(b),(d),(f), so it is correct.
\[ \boxed{(g),(a),(e),(c),(b),(d),(f)} \]
