In some African languages, verbs not only encode the timeframe of an event but also imply the origin of the speaker's knowledge, which may be direct observation, hearsay, or intuition, resulting in speakers of those languages who cannot state facts without an attribution to some source.

A) not only encode the timeframe of an event but also imply the origin of the speaker's knowledge, which may be direct observation, hearsay, or intuition, resulting in speakers of those languages who cannot state facts without an attribution to some source --- It is weird to think that encoding and implying would result in speakers who cannot state facts.

B)not only encode the timeframe of an event but also the origin of the speaker's knowledge, direct observation, hearsay, or intuition; therefore, speakers of those languages cannot state a fact without some source of attribution--- not only encode but also the origin is un//.

C) Encode not only the timeframe of an event but also the origin of the speaker's knowledge, whether direct observation, hearsay, or intuition; as a result, speakers of those languages cannot state facts without attributing them to a source --- correct choice.

D)do not encode the timeframe of an event; they also imply the origin of the speaker's knowledge -- whether direct observation, hearsay, or intuition -- resulting in the inability of those languages' speakers to state facts and not attributions to some source-- do not encode the time frame is diametrically opposite to the original intent.

E)not only encode the timeframe of an event but also imply the origin of the speaker's knowledge, direct observation, hearsay, or intuition; speakers of those languages, state and do not state facts without attributing them to sources--- do not state and cannot state are not the same.
