A wire of length 2L, is made by joining two wires A and B of same length but different radii r and 2r and made of the same material. It is vibrating at a frequency such that the joint of the two wires forms a node. If the number of antinodes in wire A is p and that in B is q then the ratio p : q is |

(a) |
4 : 9 |
(b) |
1 : 2 |

(c) |
3 : 5 |
(d) |
1 : 4 |
