For Child Relief and You, magazines would be the best media as their ads can reflect the organization's message and reach their target audience. For life insurance, television advertising allows creating ads meeting broadcast standards and placing targeted ads on TV. For mobile phone networks, mobile/online displays are most effective as ads are striking on small screens, users are attentive, and targeting is diverse. For mutual funds, posters/hoardings can only include a risk statement due to limited reading time, while TV ads must show the risk statement for 2+ seconds and audio ads clearly state it.
