(A)claims
(B)to claim
(C)claiming
(D)are claiming

按句意，逗號前的句子是引用文章的內容，逗號後的主詞是Adrienne Bernhard's “What Your Handwriting Says About You.”，句中缺少動詞

因此應使用動詞型態的(A)或(D)
而本句主詞是第三人稱單數故應選(A)claims

Our handwriting might indicate our nationalities 國籍 and educational background,   (A)claims Adrienne Bernhard's “What Your Handwriting Says About You.” Yet, Bernhard's article also indicates that the proliferation of typing--via emails, text messages, etc--might in fact undermine 侵蝕 the distinctness 明顯區別 of our handwritings. The battle for cursive has always been a battle for the uniqueness獨特 of our handwriting and ourselves, verses 詩and the evolution of technology and push towards efficiency. 
     Not too long ago, cursive--Spencerian script to be specific--“was the de facto standard writing style for business correspondence before the widespread adoption of the typewriter.” 

 (A)claims
