Answer:
Option B, to establish the reference polarity for induced voltages
Explanation:
Dot basically indicates the polarity of the electrical windings. Currents entering and leaving the same dotted ends will produce magnetic flux in same direction while the current entering at one dotted end and leaving at another dotted end will produce opposing magnetic flux.
Thus it is clear that dot represents the terminals having same phases of induced AC voltages so that only one winding is loaded at a time.
Hence, option B is correct

Hey
Your answer is the one on the bottom
Newton's first law states that objects in motion will remain in motion (unless acted on by an external force) and that objects at rest will remain at rest.
On earth, if you throw a ball it will hit the ground and the friction between the grass and ball will slow it down. If the ground was frictionless then it would keep going forever.
