Answer:
B. Blasting is an ultrahazardous activity, so Alpha is strictly liable for Li's damages even though Alpha followed best safety practices.
Explanation: Under the concept of strict liability, a person or an organisation is liable to the consequences of their actions even when they have followed the best practices and no form of Negligence have been attributed to them or their actions.
BASED ON THE CONCEPT OF STRICT LIABILITY, ALPHA WILL BE HELD LIABLE TO LI'S DAMAGES AND WILL BE EXPECTED TO TAKE THE RESPONSIBILITY FOR WHAT EVER IT COST.
