First of all , many have answered it vaccum but it is absolutely wrong because sound can not travel in vaccum and most probably the correct answer will be solid.

Ans 3:

Class : Class 8
vacuum

Ans 4:

In solids, especially when atoms are closely packed, metals.. Sound does travel in water and air with slow speed 1000, 300 m/s respectively whereas in metals with 3000 m/s.. And sound doesn't travel in vaccum at all..
