Solution:A. (books-books (Eng), Kitab-Kitābē (Hindi)) - IV: Suffixation → In both English and Hindi, the plural form is created by adding a suffix (-s in English, -ē in Hindi).
B. (Pat-papat (Sanskrit), nyāy-anyāy) - III: Prefixation → In Sanskrit, some reduplicative forms add a prefix (papat from pat). Similarly, 'a-' in 'anyãy' is a prefix.
C. (Shong-shnong (Lebasi)) - I: C-Infixation → Infixation occurs when a morpheme is inserted inside a root, as seen in 'shnong' where 'n' is inserted.
D. (Kitab-katab (Arabic)) - II: V-Infixation → In Arabic, vowel changes within a word (ablaut) represent morphological changes, as seen in kitab katab.
