B. At 7 months, the infant sits alone with some use of hands for support: This is an accurate statement. By around 6 to 8 months, infants develop the ability to sit unsupported, although they may still use their hands for balance.
C. At 9 months, the infant crawls with the abdomen off the floor: Crawling typically begins between 7 and 10 months, but the abdomen may still be close to the floor initially.
D. At 1 month, the infant lifts and turns the head to the side in the prone position: This is an accurate statement. Newborns typically exhibit head control and turning movements when placed on their stomachs (prone position) by around 1 month of age.

E. At 2 months, the infant rolls from supine to prone to back again: Rolling from supine to prone and back may begin around 4 to 6 months, but it's less likely to occur at 2 months.
