It Is Spring,and Several Graduates of State U Are Seeking

It is spring,and several graduates of State U are seeking employment.State U graduates have evenly distributed GPAs,from 2.0 to 4.0,with an average GPA of 3.0.The largest employer in town,Acme Dynamite,is interviewing candidates,hoping to hire a few hard workers.While Acme does not require students to submit a transcript with their applications,the hiring officer believes that high GPAs signal a willingness to work hard.
Acme has received applications from 10 graduates of State U.Five included transcripts,all of which indicated GPAs of 3.5 or better.Acme can infer that the five that did not include transcripts

A) had GPAs of less than 3.0.
B) read the application instructions more carefully.
C) had GPAs evenly distributed between 2.0 and 4.0.
D) had GPAs between 2.0 and 4.0,but can infer nothing else from the lack of transcripts.
