a) Higher the LLR, higher the amount of explosive
b) Higher the LLR, lesser the amount of explosive
c) 10% more explosive for every 1m of LLR
d) 10% less explosive for every 1m of LLR

Answer: a
Explanation: LLR is the shortest distance travelled by the expelled gasses on blasting through a path which offers least resistance. Therefore, higher amount of explosives will result in higher LLR.
