The answer to your question is the second choice
Explanation:
Formula to calculate the heat of any substance
Q cal= mCcal ΔTcal
Formula to calculate the heat of a metal. The heat will be negative because it releases heat.
Qm = -mCmΔTm
Now equal both formula
Qcal = Q m
mCcalΔTm = -mCmetΔTmet
-Solve for Cmet
Cmet = -[mCcalΔTm] / mΔTmet
