1. Correct Answer: Option B: 4:10 p.m.
 2. Explanation:
     To determine when the three signals will next turn green simultaneously, we need to find the least common multiple (LCM) of the time intervals for each signal to complete a full cycle (from green to red and back to green).
     ● Signal 1: Completes a full cycle in 25 seconds.  
     ● Signal 2: Completes a full cycle in 39 seconds.  
     ● Signal 3: Completes a full cycle in 60 seconds.  
     Step-by-step Calculation:
     ● Find the LCM of 25, 39, and 60:  
           ○ Prime factorization:
             ○ 25 = 5²
             ○ 39 = 3 × 13
             ○ 60 = 2² × 3 × 5
           ○ LCM is found by taking the highest power of each prime number that appears in the factorizations:
             ○ LCM = 2² × 3 × 5² × 13
           ○ Calculate:
             ○ 2² = 4
             ○ 3 = 3
             ○ 5² = 25
             ○ 13 = 13
           ○ LCM = 4 × 3 × 25 × 13 = 3900 seconds
     Convert 3900 seconds to hours and minutes:
         ○ 3900 seconds ÷ 60 seconds/minute = 65 minutes
     Add 65 minutes to 2:00 p.m.:
         ○ 2:00 p.m. + 65 minutes = 3:05 p.m.
     Therefore, the signals will next turn green simultaneously at 3:05 p.m., not 4:10 p.m. as initially stated in the question. It seems there was an error in the provided answer. The correct time should be 3:05 p.m.
