What pair of statements about Blehert's and Behr's work represent an observation that was first made directly in the field and then a repeat, reinforcing observation made in the lab?

A). A microbiologist with the U. S. Geological Survey grew crescent-shaped fungal spores in a lab on refrigerated plates.

C). A specialist with the New York State Health Department detected crescent-shaped fungal spores when examining a sample swabbed directly from a living bat with a white nose.

Explanation:

As per the question, the above-given couple of statements about Blehert and Behr's work display an observation that was initially made straight in the field as reflected by option C ('detecting a crescent-shaped fungal spores directly from the living bat having a white noise') and then, a replicate bracing observation that was made in the lab as mirrored by option A ('the microbiologist's growing of crescent-shaped fungal spores in the lab on refrigerated plates'). Therefore, options A and C are the correct answers.
