Answer :
Final answer:
Shroomite Armor boosts only ranged damage, with specific bonuses for ranged combat. It does not boost melee damage. Other armors listed provide different bonuses for magic, ranged, or melee with various additional effects.
Explanation:
The armor set referred to in the question that boosts only melee and ranged damage is d) Shroomite Armor. Shroomite Armor is a post-Plantera armor set that provides bonuses to ranged weapons. Each piece of the armor set can be crafted at an Autohammer, which itself is only available after defeating Plantera and purchasing from the Truffle NPC. The Shroomite Armor does not directly increase melee damage; it is specifically designed to enhance ranged combat proficiency by providing bonuses like increased ranged damage and critical strike chance, as well as reducing enemy visibility to the player when standing still.
As for the other options, a) Spectre Armor provides magic damage and utility bonuses, b) Chlorophyte Armor offers various bonuses depending on the headpiece chosen (melee, ranged, or magic), c) Turtle Armor boosts defense and melee damage while applying a Thorns-like effect, and e) Beetle Armor which comes in two variants also boosts melee damage, either focusing on offense with the Beetle Scale Mail or on defense with the Beetle Shell.
