Answer: a
Explanation: Curl is defined as the circulation of a vector per unit area. It is the cross product of the del operator and any vector field. Circulation implies the angular at every point of the vector field. It is obtained by multiplying the component of the vector parallel to the specified closed path at each point along it, by the differential path length and summing the results.

Explanation:
Curl of a Vector Field:
- The curl of a vector field is a measure of the rotation or angular velocity of the vector field at every point.
- It is a vector operator that gives a vector field as an output.
Definition of Curl:
- Mathematically, the curl of a vector field F, denoted by ∇ x F, is defined as the cross product of the del operator (∇) and the vector field F.
- The curl of a vector field F = (P, Q, R) is given by the formula:
∇ x F = (dR/dy - dQ/dz)i + (dP/dz - dR/dx)j + (dQ/dx - dP/dy)k
Angular Velocity:
- Angular velocity is a measure of how quickly an object rotates or revolves around a particular axis.
- It is a vector quantity, and its direction is along the axis of rotation.
Relation between Curl and Angular Velocity:
- The curl of a vector field can be thought of as representing the local angular velocity of the vector field.
- At each point in the vector field, the curl gives the axis of rotation and the magnitude of rotation.
Conclusion:
- Therefore, the statement that curl is defined as the angular velocity at every point of the vector field is True. It accurately describes the relationship between the curl of a vector field and the concept of angular velocity.
