(A)①②③
(B)①②④
(C)①③④
(D)②③④

其實都不太對，多毛症是馬的腦下垂體中間部功能不全所導致

且看原文書怎麼說，對我懶得翻譯

Although it has been called equine Cushing’s disease, its pathogenesis is distinct from that of human or canine Cushing’s disease.

Whereas Cushing’s disease reflects an aberration in the hypothalamic-pituitary-adrenal axis control of corticotrophs,
pars intermedia melanotrophs do not express glucocorticoid receptors and are controlled instead by dopaminergic inhibition from hypothalamic neurons.

Importantly, the adrenal glands of horses with PPID are usually unremarkable—that is, they are free of diffuse or nodular proliferation of cortical cells.
