Answer: A

Explanation:

Steps involving in calculating risk priority number are as follows:

– Identify potential failure effects

– Identify potential causes

– Establish links between each identified potential cause

– Identify potential failure modes

– Assess severity, occurrence and detection

– Perform score assessments by using a scale of 1 -10 (low to high rating) to score these assessments.

– Compute the RPN for a particular failure mode as Severity multiplied by occurrence and detection.

RPN = Severity * Occurrence * Detection

Hence,

RPN = 4 * 5 * 6

= 120

Incorrect Answers:

B, C, D: These are not RPN for given values of severity, occurrence, and detection.
