Confused about Voluntary Abetment vs. Criminal Conspiracy

Maine suna hai ki voluntary abetment aur kriminal conspiracy dono hi IPC ka section 120B ka aapda hain, lekin kya difference hai inmein? Kya voluntary abetment sirf tab hota hai jab koi vyakti doosre ko kuch karne ke liye prerna de raha hai, aur kriminal conspiracy toh tab hota hai jab aisi prerna milne ke baad koi action hoti hai?

Mujhe laga hai ki ismein kuch confusion hai. Kya kisi ko sirf voluntary abetment ke liye punishment mil sakti hai, ya phir kisi ko conspiracy ka charge laga ja sakta hai? Aur kya dono hi sections mein abetment ki definition same hai ya nahin?
