I practiced a question similar to this, and I think the key point was about the short distance and line-of-sight requirements for infrared.

I'm not entirely sure, but I feel like the equipment needed for infrared eavesdropping is more complex than for radio transmissions.

I think I read somewhere that infrared needs a direct line of sight, which makes it harder for eavesdroppers to pick up the signal.

I remember studying that infrared signals are less likely to be intercepted because they don't travel as far as radio waves.

This looks like a compound interest problem. I'll need to calculate the future value of the monthly investments over the first 12 years, then add the fixed payments for the next 12 years.

I'm pretty sure the Kanban approach is about visualizing and controlling work in progress, so I'll go with option A.
