B. between G1-S phase. DNA sythesis starts from S phase doubling the amount of DNA. Until the two cells divide at M phase, S, G2 and M phase cells contain DNA twice as much as normal cells. Interphase composed of Go, G1 (the same amount of DNA as normal cells), S and G2(twice amount of DNA compared to normal cells). So it is not correct entirely. M phase cells has twice amont of DNA at start and after cytokinesis possess the same amount of DNA as normal cells. So it is not lowest.
