Select the statements that correctly link each type of enzyme deficiency with the metabolites that accumulate in the blood and tissues.

(a) a transferase deficiency will cause an accumulation of udp‑glucose.
(b) a deficiency in either enzyme will result in an accumulation of lactose; however, a transferase deficiency will also cause an accumulation of the toxic product udp‑galactose.
(c) a galactokinase deficiency will result in an accumulation of galactose 1‑phosphate. transferase converts galactose 1‑phosphate to udp‑galactose; therefore, a transferase deficiency will cause an accumulation of galactose 1‑phosphate.
(d) a galactokinase deficiency will cause an accumulation of galactose.
