Answer: A, Immunotactoid
Immunotactoid Glomerulopathy is characterized by parallel microtubular deposits with lucent cores which are classically greater than 30 nm by electron microscopy. Both fibrillary and amyloid fibrils are typically characterized as non-branching randomly oriented fibrils which range usually between 10-20 nm and 7-12 nm, respectively. Light chain deposition disease classically shows characteristic punctate, powdery deposits within glomeruli and tubular basement membranes by electron microscopy.
