Please help me ..im begging you​
Deffense [45]

Explanation:

let's assume that:

v1= 600ml=0,6l

T1=27°C= 300K

p1=700mmHG=93326Pa

T2=-20°C=253K

p2=500mmHg=66661

V2=?

p1V1/T1=p2V2/T2 => V2=p1V1T2/p2

V2= 93326*0,6*253/66661

V2=212,52l

option a is correct because here serves, rotation and spikes all the three words are using as object.

The volleyball team practiced their serves, rotations, and spikes.

Again option d cannot be correct because  in this option ""spikes over the net" spikes is used as a verb  which can be used in present indefinite form of sentence only but here sentence is in past indefinite form.
