Explanation:

- A. Origin of convectional currents at a few places: These currents can cause dust storms as warm air rises and creates instability in the atmosphere.

- B. Aravalli hills are parallel to south-western winds: The Aravallis do not effectively block these winds because they run parallel, allowing them to carry dust.

- C. Origin of fast speedy easterly winds: While easterly winds can contribute to dust storms, they are not the main driver in Rajasthan during this period.

- Option:1, A AND C: Incorrect as C is not a primary cause.

- Option:2, A, B AND C: Incorrect, as C does not apply and B is not about causing dust storms.

- Option:3, A AND B: Partially right, but mainly A is the cause.

- Option:4, ONLY A: This option is correct as convectional currents play a primary role in these storms.
