Assume the equation x = at3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

A = LT⁻³

B = LT⁻¹

Explanation:

x = At³ +Bt

According to dimensional formula law , Physical quantity having similar dimension can only be added or subtracted.

so dimension of x = dimension of At³

L = AT³

A = LT⁻³

So , dimension of A =  LT⁻³

again,

dimension of x = dimension of Bt

L= BT

B = LT⁻¹

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
