With no explanation, chose the best option from "A", "B", "C" or "D". an interlocutory order. “Generally, there is no right of immediate appeal from interlocutory orders and judgments.” Sharpe v. Worland, 351 N.C. 159, 161, 522 S.E.2d 577, 578 (1999). N.C. Gen. Stat. § 7A-27(d)(l) (2009), however, authorizes an appeal from an interlocutory order that affects a substantial right. “[W]hen, as here, a party asserts a statutory privilege which directly relates to the matter to be disclosed under an interlocutory discovery order, and the assertion of such privilege is not otherwise frivolous or insubstantial, the challenged order affects a substantial right under sections l-277(a) and 7A-27(d)(1).” Sharpe, 351 N.C. at 166, 522 S.E.2d at 581. This appeal is, therefore, properly before us. See Armstrong v. Barnes, 171 N.C. App. 287, 290-91, 614 S.E.2d 371, 374 (<HOLDING>), disc. review denied, 360 N.C. 60, 621 S.E.2d

C: holding that an order was interlocutory in nature despite the trial courts certification of the order as a final appealable judgment
