Very generally, excretion is the removal of substance from the body (micturition or defecation are good examples). Tubular excretion is probably referring to excretion of (filtrate, now urine) from the collecting duct of a nephron. Beyond the collecting duct, almost no secretion or absorption occurs, hence all substrate is excreted (NOT the same as secreted).
Papillary duct or DCT The thing in this question that stands out to me is "part of the nephron". Actually the parts of a nephron only include renal corpuscle, proximal convoluted tuble, nephron loop, and distal convoluted tubule. I would a say the answer, if you read it the way I am taking it, is DCT. The papillary duct does follow the DCT but is not part of the nephron.
No, the collecting duct is the site where the filtrate from multiple nephrons is collected and the final adjustments to urine concentration are made. The distal convoluted tubule drains into the collecting duct.
Papillary Duct
The distal convoluted tubule is the portion of the nephron that empties into the collecting ducts. It is the last segment of the nephron.
Urine
Distal Convoluted Tubule
Yes, a very small one.
collecting duct is connected to the ureters.
collecting duct (system) and late distal tubule
A nephron is composed of the Bowman's capsule, the proximal tubule, the loop of the nephron (called the loop of Henle), the distal tubule, and the collecting duct.
