A) 87
B) 71
C) 57
D) 43
E) 29
Fragment Peaks
Fragment peaks in mass spectrometry refer to the peaks that represent the masses of fragments from the molecule being ionized and broken apart, aiding in the determination of molecular structure.

Final Answer :
A
Explanation :
A fragment peak at m/z 87 would indicate the loss of a methyl group and a tertiary carbocation, which is not possible in n-hexane. The other fragment peaks listed (m/z 71, 57, 43, and 29) are all possible in the mass spectrum of n-hexane.
