At a products liability trial, one of the most critical issues is whether the temperature was below freezing on January 16. Akiro does drafting work at an architectural and civil engineering firm, but Akiro is also an avid amateur meteorologist. The backyard of Akiro's home is rigged with many weather detection instruments that track wind, temperature, humidity, barometric pressure, and precipitation. One of Akiro's instruments records temperature by markings from a stylus on a round barograph. Akiro's record of the day in question indicates that it was unseasonably warm and that the temperature never fell lower than 48 degrees Fahrenheit, 16 degrees above the freezing mark. The plaintiff offers into evidence Akiro's barograph record of the temperature on January 16. The barograph record is:
A. Admissible, as past recollection recorded.
B. Admissible, as a record of regularly con- ducted activity.
C. Inadmissible, unless foundation testimony is given as to the accuracy and good working order of Akiro's instrument on the day in question.
D. Inadmissible, because it is hearsay not within any recognized exception to the hearsay rule. 
Choose A, B, C or D as your solution.
