Target entity: Neogrammarian hypothesis of sound laws
Context triple: [Grimm's law, influenced, Neogrammarian hypothesis of sound laws]

A. Verner's law
Verner's law is a historical linguistic principle explaining a systematic set of consonant alternations in the Germanic languages that refined and expanded upon Grimm's law.
B. Grimm's law
Grimm's law is a fundamental linguistic principle describing the systematic consonant shifts that distinguish the Germanic languages from other Indo-European branches.
C. Ingvaeonic nasal spirant law
Ingvaeonic nasal spirant law is a historical sound change in early Germanic languages that caused the loss of nasal consonants before fricatives, leaving characteristic vowel changes in Anglo-Frisian and related dialects.
D. High German consonant shift
The High German consonant shift was a major sound change in early Germanic dialects that transformed the consonant system and helped distinguish High German (and related varieties like Lombardic) from other West Germanic languages.
E. Indo-European phonology
Indo-European phonology is the branch of linguistics that reconstructs and analyzes the sound systems and sound changes of the Proto-Indo-European language and its descendant languages.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
