So when you're given a decay equation, how do you know if it's strong or weak? I know that if strangeness isn't conserved (and there's neutral particle(s) involved) it has to be a weak interaction, but otherwise...??

This is the past paper question that got me confused.
For part (b) the answer is strong nuclear, and for part (d) it is weak nuclear.
Part (d) makes sense in my head, but I was confused about part (b), and when I looked it up on Google, this website (https://www.cyberphysics.co.uk/Q&A/K...ticle/A11.html) said that part (b) is a strong interaction because weak interactions must involve leptons. But that contradicts with the answer to part (d), as X must be a baryon.
Someone please help me out...!
