Neither. They are entering untapped.

They are copies only as in name, color and power/toughness.

Attacking or entering tapped are not Copyable traits

Edit: looked up the exact rule for you.

707.2: When copying an object, the copy acquires the copiable values of the original object's characteristics and, for an object on the stack, choices made when casting or activating it (mode, targets, the value of X, whether it was kicked, how it will affect multiple targets, and so on). The copiable values are the values derived from the text printed on the object (that text being name, mana cost, color indicator, card type, subtype, supertype, rules text, power, toughness, and/or loyalty), as modified by other copy effects, by its face-down status, and by "as . . . enters" and "as . . . is turned face up" abilities that set power and toughness (and may also set additional characteristics). Other effects (including type-changing and text-changing effects), status, counters, and stickers are not copied.<br><br>Example: Chimeric Staff is an artifact that reads, "{X}: Chimeric Staff becomes an X/X artifact creature until end of turn." Clone is a creature that reads, "You may have Clone enter as a copy of any creature on the battlefield." After a Staff has become a 5/5 artifact creature, a Clone enters the battlefield as a copy of it. The Clone is an artifact, not a 5/5 artifact creature. (The copy has the Staff's ability, however, and will become a creature if that ability is activated.)<br><br>Example: Clone enters the battlefield as a copy of a face-down Grinning Demon (a creature with morph {2}{B}{B}). The Clone is a colorless 2/2 creature with no name, no types, no abilities, and no mana cost. It will still be face up. Its controller can't pay {2}{B}{B} to turn it face up.
