Question

a protostar
usually has a stellar wind & eclipsing exoplanets around it
fuses hydrogen into helium, but at a lower rate than during the main - sequence phase
usually has an accretion disk with jets

Explanation:

A protostar is in the early - stage of star formation. It is surrounded by a rotating accretion disk from which jets can be emitted. Stellar winds and eclipsing exoplanets are not typical features of protostars. Protostars do not fuse hydrogen into helium at a significant rate as they are still in the gravitational - contraction phase before reaching the main - sequence hydrogen - fusion stage.

Answer:

usually has an accretion disk with jets
