Explanation:

First let us write out the formula relating the period(T),mass(m) and spring constant(k)

let assume

hence w can write the formula as

if we vary k, we arrive at

Now if the mass was doubled,

we arrive at

Since

b.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
