The ITU’s G.114 recommendation specifies that the one-way delay between endpoints should not exceed 150 ms to be acceptable, commercial voice quality. The ITU G.114 recommendation specifies that 151 ms to 400 ms on-way delay might be acceptable provided that organizations are aware that the transmission time will affect the quality of user applications. One-way delays above 400 ms are unacceptable for general network planning purposes.
I go with d) 0-150ms
wrong answer is DEF
>400ms delay is unacceptable for general network:
