No way it's C, that method seems off.

I practiced a similar question, and I feel like the Plus tool is definitely involved, but I'm not sure about the truncation part.

I think the method involves adding something to the pixel values, but I can't remember if it's 0.5 or 1.

I'm not too familiar with the Spatial Analyst tools, so I'm not 100% sure about the best approach here. I'll need to review the tool descriptions to make sure I select the right method.

Okay, I've got this. The key is to use the Spatial Analyst tools to round the decimal values to the nearest whole number. D looks like the right approach - add 0.5 and then truncate to the nearest integer.

I heard they're making a new GIS tool called the 'Round and About' tool. It's perfect for when you just can't make up your mind about rounding.

Option D for sure! Who needs all those extra steps when you can just add 0.5 and truncate? Easy peasy lemon squeezy!

Hmm, this is a tricky one. I'm tempted to go with option C, but I'm not sure if that's the most efficient way to round the pixel values. Gonna have to think this one through.

I'm pretty sure I've used the Round Up and Round Down tools before, but this question is making me second-guess myself. Maybe I should review the Spatial Analyst tools again.
