In a minimum phase system
all poles lie in the left half plane
all zeros lie in the left half plane
all poles lie in the right half plane
all except one pole or zero lie in the left half plane
Answer: Option
Explanation:

For stability poles must be in left half plane. Zeros in left half plane lead to minimum phase shift.

I did not understand this explanation. Please explain it in detail.

For stable system it is necessary that poles should be in left of the plane but for minimum phase system Zeros Should be in left half of the plane.

Minimum phase systems are stable systems without dead time. Option A should not be among the Options.

A question should have only one unequivocal answer.
